摘要
采用羧甲基壳聚糖对两种染料溶液和印染废水进行处理 ,研究 p H、添加量、温度、时间对废水脱色的影响 .结果表明 ,羧甲基壳聚糖对水溶性染料及印染废水具有良好的脱色效果 .在 p H=6～ 7的范围内 ,且添加量为 0 .6 g· L-1、温度为 35℃时 ,脱色效果最好 .处理 2 4 h后 ,脱色率可达 90 % .
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.
