かった。Chitin-based substances include chitin, chitosan, and their derivatives, which are effective in removing glucosamine polymers, heavy metals (especially) Ig, Cd, and Cu, and organic matter, and also have bactericidal and insecticidal effects. There is. No microbial growth was observed even if the product was left unused for a long period of time.
キチンは節足動物、中でもカニ、エビ等の甲殻類の皮殻
と脱灰、脱蛋白して得られる。Chitin is obtained by decalcifying and deproteinizing the skins of arthropods, especially crustaceans such as crabs and shrimps.
キトサンはキチンを濃苛性ソーダ水溶液中で熱処理して
脱アセチル化されたものである。Chitosan is made by deacetylating chitin by heat-treating it in a concentrated aqueous solution of caustic soda.

0% by weight of chitosan is dissolved in an aqueous solution containing an acid such as hydrochloric acid or acetic acid, and a predetermined amount of powdered activated carbon is added to the paste).
Create. Next, when an aqueous solution of an alkali such as caustic soda or caustic potash is added to the mixture while stirring, chitosan is precipitated in the form of agglomerated activated carbon. This is separated from water or purified by tilt washing or filtration, and then either strongly compressed to remove water, or slightly dried to lower the water content. This is made into granules using a granulator such as a meat chopper, and dried to produce a water purifying agent for water purifiers. Also, to make it into granules,
When the above paste is dropped into an alkaline aqueous solution through a fine-tipped tube while stirring, it becomes porous spherical particles. (3) Add the following after the first line of page 6.
