| Abstract: | Raff of organic and inorganic impurities is produced in extracting L-cystine from goat bristles. This paper analyses the forming process of the impurities and their influence on product yield and quality. Physical chemistry method was used to remove the impurities, which were decolorized by activated carbon two times and neutralized by recrystallization three times. The product quality has come up to high level of GH 2030-91. |
