摘要：利用硅藻土负载壳聚糖季铵盐处理甲基橙染料废水,考察了季铵盐取代度、添加量、温度、甲基橙初始浓度、pH值和作用时间对甲基橙脱色率的影响。结果表明,壳聚糖季铵盐的季铵化取代度为55.6%时,硅藻土/HACC2对甲基橙的脱色效果最好。当pH值为2.6,20℃下搅拌90min,硅藻土负载壳聚糖季铵盐添加量为350mg时,对50 mL质量浓度为0.05mg/mL的甲基橙染料去除率达95.3%。
This paper examined the adsorption of diatomite loading quaternary ammonium salt of chitosan treating methyl orange, from the aspects of degree of substitution, adsorbent dosage, temperature, initial concentration of methyl orange, pH value and mixing time. The results showed that D/HACC2 had the best decolonization effect towards methyl orange, while the substitution degree of chitosan quaternary ammonium salt was 55.6%. The decolorization rate of methyl orange in 50 mL is 95.3 %, when the pH value is 2.6, stirring time is 90 min, adsorbent dosage is 350 mg and the initial concentration of methyl orange is 0.05 mg/mL.
