摘　　要：通过将壳聚糖进行烷基化,用于染料废水的脱色,探讨了染料溶液的pH值、温度、搅拌时间、搅拌速度、改性壳聚糖添加量对染料脱色效果的影响。结果表明:在pH值7、温度20℃、搅拌时间10 min、搅拌速度200 r/min、改性壳聚糖用量分别为0.10和0.08 g/L时,0.15 g/L的活性染料M-3B和直接蓝5B染料溶液获得最佳脱色效果。Alkylated chitosan was synthesized and used to deal with dyeing wastewater.The influence on discoloration effect under the conditions of different pH,temperature,stirring time,stirring speed and modified chitosan dosage was studied.The results showed that：at pH=7,temperature 20℃,stirring time 10 min,stirring speed 200 r/min,the 0.15 g/L reactive red M-3BE and direct blue 5B solution had the optimum decolorization effects by treated with the dosage of modified chitosan 0.10 g/L and 0.08 g/L.
