描述

Analysis Note

The degree of acetylation may be determined by dye binding7 or titration methods8.

Preparation Note

Prepared by the alkaline deacetylation of chitin obtained from the shells of shrimp (Pandalus borealis). Chitin is manufactured industrially by crushing shrimp shells, then washing the solids with acids to remove inorganic and proteinaceous material. The purified chitin is deacetylated to chitosan by treatment with a strong base such as sodium hydroxide. The resulting chitosan may be further purified by preparation of solutions in acid followed by neutralization and precipitation.

Quality

May contain foreign matter.

Application

与多价阴离子形成胶体。形成透明溶液,干燥后可形成透明坚韧的膜。

Features and Benefits

兼具生物兼容性、抗菌性和环保性的聚电解质,可应用于各个领域,1包括水处理、色谱、化妆品添加剂、纺织品抗菌处理、2新型纺织纤维、相纸、生物降解薄膜,3生物医疗仪器以及施药缓释微囊植入物。4,5,6
