壳聚糖—二氧化钛对酸性品红染料废水脱色的研究

Study on Treatment of Acid Fuchsin Dye Wastewater by Chitosan-Titanium Dioxide

本文对比了壳聚糖—二氧化钛及壳聚糖对酸性品红染料废水的脱色性能,研究了酸性品红初始浓度、温度以及二氧化钛和壳聚糖配比、投加量等因素对于酸性品红脱色性能的影响.实验结果表明:常温下,酸性品红初始浓度为5 mg/L时,壳聚糖投加量为1.0 g时,最高脱色率为93.80%;同样条件下,配比为30:5的壳聚糖—二氧化钛的投加量仅为0.10 g,脱色率可达92.45%,其用量明显少于壳聚糖.

In this paper,it compared decoloring effect of acid fuchsin by used chitosan and titanium dioxidechitosan.It studied the impact on the decoloring effect of initial concentration of the acid fuchsin,temperature,the proportion of titanium dioxide and chitosan,dosing quantity.The results showed that the best decoloring effect were 1.0 g of chitosan by the concentration of 5 mg/L acid fuchsine,and the best decoloring rate was 93.80%.When the ratio of chitosan-titanium dioxide were 30:5,and adding 0.10 g to 5 mg/L acid fuchsine solution,the decoloring rate was 92.45%.Its dosage was significantly less than chitosan.
