【Abstract】 Carboxymethyl chitin is adopted to treat two kinds of dye and the effluent from textile printing. A study is devoted to the efects of pH, amount of addition, temperature and time on the decoloration of the effluent. The result shows a good decolorizing effect of carboxymethyl chitin on water soluble dye and dyeing effluent from textile printing, with a rate of decolorization up to 90% can be attained after treatment for 24 hours.更多还原
