ALGINIC ACID MATERIALIZATION METHOD USING WASTE SEAWEED AND ENZYMES

The present invention relates to an alginic acid materialization method using waste seaweed and enzymes. The method comprises: a material preparation step of collecting waste seaweed and washing off salt and attached matter, and then, smashing the waste seaweed; an enzyme treatment step of putting the waste seaweed in a fermentation bath, adding enzymes, and conducting stabilization; a sulfuric acid extraction step of extracting and swelling a sulfuric acid solution; an alkali treatment step of removing filtrate and injecting a sodium carbonate solution into residues for extraction; a filtration step of forming shaking liquid with water and conducting decompression filtration; an acidic treatment step of adding hydrogen chloride to the filtrate to regulate the pH to an acidic level; a centrifugation step of adding ethanol and sodium hydroxide to precipitates, from which a supernatant has been removed through centrifugation, to regulate the pH to a neutral level; a solvent washing step of ...
