What is Algin Acid?

Alginic acid is a thick all-natural acid, in addition called alginic acid and alginic acid. The product is white to light yellow-brown powder. The typical molecular weight has to do with 240,000. Melting point > 300 ° C. A little soluble in hot water, the density of its liquid treatment is 4 times higher than that of starch, insoluble in cold water and also natural solvents, slowly soluble in alkaline remedy. Odorless. It is thoroughly existing in the cell wall surface areas of numerous brownish algae such as big algae, kelp, kelp, fucus in addition to sargassum in nature, amongst which the algae of Laminariaceae have a huge content (worrying 20% usually), and likewise most of them exist in the form of calcium along with magnesium salts.
Algin Acid is a straight block polyuronic acid, that includes homopolymerized α-L-pyranuronic acid block, homopolymerized β-D-pyranuronic acid block along with this The cross-polymerized blocks of 2 uronic acids are linked by 1,4-glucosidic bonds. Exist in the cell wall surface areas of numerous marine brown algae in the form of calcium, magnesium, salt, potassium, strontium salts, and more. Industrially made up of macroalgae, claus kelp, palmate kelp, sugar kelp, kelp, kelp L. ochotensis, kelp antenosa, ascophyllumrodosum, staghorn algae, fucus vesiculosus, Nitella serrata, Haixiang algae, kelp in addition to winged algae (Alaria) are extracted. The fundamental removal technique is: after the raw algae is cleaned, it is absorbed with antacids to make alginic acid establish a soluble antacids steel salt, filter, as well as also include acid to precipitate alginic acid. Alginic acid can furthermore be converted into sodium, potassium, ammonium, calcium salt or various other all-natural spin-offs, collectively called algin (aglin). Industrial algin mostly refers to salt alginate.
Free alginic acid is a white strong. Insoluble in cold water, a little soluble in hot water. It is acidic and has acid resistance, yet it is conveniently rotted by warm antacids. Concentrated hydrochloric acid decarboxylation happens. It has a particular discerning adsorption result on steel ions, especially Fe(II) ions. Its alkali steel salt and also ammonium salt liquify in water to create a thick fluid, however it is tough to create a gel. Converts to insoluble alginic acid gel or speed up listed here pH3. Adding polyvalent steel ions (such as calcium chloride) makes it straightforward to gel. Sodium salt is light yellow powder, insoluble in natural solvents, [a] D-139 °. Alginate is extensively made use of in industries such as food, textile printing along with dyeing, papermaking, medication, all-natural leather, cosmetics, rubber, paint as well as also water treatment.

Algin Acid Uses

Algin Acid can rapidly take in water and also can be utilized as a drying out agent and also sizing agent in paper and also fabric industries. Its major feature is that it is made use of as an emulsifier or thickener in the food market and also everyday chemical industry in the form of salt alginate or potassium alginate. It is a typical ingredient in food and also cosmetics such as ice cream and also milkshake.

In the pharmaceutical market, Algin Acid is a commonly utilized excipient: its thickness makes it a tablet binder; since it swells with water, it is used as a disintegrant to distribute the tablet computer system in the human body; or as a Dispersants disperse the energetic active ingredient into a liquid ahead to be a suspension; alginate is made use of as a medication launch representative. Dental therapy utilizes it to alter plaster along with rubber to make oral styles. Alginic acid itself can be made use of as an absorbent to manage heavy metal poisoning.

Synergistic Effect of Algin Acid on Fertilizers

1. The energetic ingredients of Algin Acid can enhance the application rate of fertilizers.
1. The algae polysaccharides (alginic acid, fucoidan, algae starch, cellulose, etc) in the alginic acid concentrate have great hydrophilicity and high solubility. Alginic acid is a polymeric carboxylic acid (-COOH), which can integrate with K+, Na+, NH4+ as well as various other monovalent cations to develop water-soluble alginate. The ion binding capability is solid, and also it has the functions of fixing nitrogen, releasing phosphorus, launching potassium, as well as turning on micronutrient in the medium. It reduces the volatilization of nitrogen and also the loss of nitrogen in the denitrification response in anoxic atmosphere, and the circumstance that the bound phosphorus is dealt with and also tough to move in the dirt is altered. Under the activity, the fertilizer result is prolonged and also the effective price is obviously enhanced.

2. Betaine, mannitol, and cytokinin in Algin Acid concentrate can promote the synthesis of chlorophyll in plants, speed up the synthesis, transport as well as accumulation of photosynthetic products; at the same time, advertise the development of plant origins as well as improve the capacity to absorb water and plant food. Under the action of leaf transpiration pull, the absorption and utilization of soil water and nutrients are sped up.

3. The organic iodine in Algin Acid can promote biological oxidation, accelerate the disintegration of original healthy protein, the synthesis of brand-new healthy protein, and the metabolic improvement of fat and sugar. The life activities of plants speed up the improvement as well as absorption procedure of plant foods as well as raise plant food performance.

4. Algin Acid foliar fertilizer, the surface stress of the plant leaves is much less than that of pure water. After splashing, a layer of alginic acid solution movie is based on the plant leaves, to ensure that the active materials in the solution, including mineral ions, promptly Passes through the cell membrane layer and goes into the cell to apply its fertilizer impact.

5. Algin Acid organic active substance, on the property of controling the physical as well as chemical homes of dirt, boosting dirt leaks in the structure, as well as preserving plant food and water, the reproduction rate and organic task of advantageous organic bacteria are enhanced, and its secretions help nitrogen addiction as well as phosphorus dissolution (Change of natural phosphorus and also repaired phosphorus) and also promote reliable application of potassium, calcium, magnesium, zinc, iron, copper, boron, molybdenum and also other components.

2. The alginic acid value-added plant food has full nourishment and also can minimize crop deficiencies.
The value-added fertilizer developed by the combination of alginic acid remedy as well as mineral formula fertilizer not only contains organic nutrients such as amino acids, algae protein, glucose, nucleotides, vitamins, organic phosphorus, etc required for crop growth, but additionally includes nitrogen, phosphorus, potassium, calcium, magnesium, as well as sulfur necessary for plants, iron zinc copper manganese boron molybdenum chloride and also beneficial components silicon iodine selenium as well as various other mineral nourishment, full nutrition. Mineral nutrient aspects and alginic acid practical groups are combined in the form of complexation (chelation) to raise as well as extend plant food performance. Alginic acid value-added fertilizer has full nourishment and long fertilizer effect, which can prevent crop deficiency as well as premature aging.

3. The energetic components of alginic acid help to boost the safety and security of fertilizers.
As a result of the solitary structure of chemical fertilizers, the performance of being soaked up by plants in the dirt is impacted by numerous elements such as dirt raw material content, ph worth, soil bit framework, salt material, dirt solution ion proportion, plant kind and also planting setting. Poor and unstable. The natural materials and also energetic substances in Algin Acid can boost the buffering ability of the dirt, enhance the dirt structure, adjust the state of soil water, fertilizer, gas and heat, and transform the conversion mode of chemical plant foods (reduce the problems of gasification, salinization, and also plant food damage), which is beneficial to Change of aspects of plant uptake and usage. The security, environmental management and also safe efficiency of plant foods are substantially enhanced.

Algin Acid Production Method

Alginic acid is widely present in the cell wall surfaces of thousands of brownish algae such as large algae, kelp, fucus, as well as sargassum, and also a lot of them exist in the form of calcium and also magnesium salts. The approach for preparing alginic acid is to extract the algae with sodium carbonate aqueous remedy, and then refine it with hydrochloric acid or calcium chloride. The procedure is as follows: include sodium carbonate to the kelp after drawing out iodine, heat it to 60-80 ° C, keep it warm as well as stir for 2 hrs, to make sure that the calcium alginate in the kelp develops sodium salt and also dissolves in water. Include a small amount of formaldehyde to repair the pigment to enhance the color of the completed item. Divide the saturating liquid and dilute with water. Pressure via a 30 mesh display. And remove slag by emulsification floating approach. After that carefully filter through a 100-mesh filter to obtain an unrefined filtrate. Add hydrochloric acid to the fine filtrate to pH = 2, to ensure that salt alginate is totally free to develop alginic acid and speed up in gel form, as well as 5% calcium chloride is contributed to advertise dehydration of the gel. Press and also filter with a press to maintain the water web content of the alginate gel listed below 75%.
