摘要
以改性亚麻为吸附剂,含有染料甲基紫的溶液为模拟废水,考察吸附剂的吸附性能。利用响应面设计实验,分析改性温度、吸附时间、吸附剂用量对吸附剂吸附量和去除率之间的相互影响。结果表明:改性温度55℃、吸附时间120 min,吸附剂用量为0.1 g条件下吸附量和去除率分别为39.65 mg/g和99.26%。
The adsorption properties were investigated based on modified flax as adsorbent and methyl violet solution as simulated wastewater. According to the Response Surface Method,the interaction effects of modification temperature,adsorption time and adsorbent dosage on adsorption capacity and removal rate were analyzed.The results showed that the adsorption capacity and removal rate were 39. 65 mg/g and 99. 26% under the modification temperature of 55 ℃,adsorption time of 120 min and adsorbent dosage of 0. 1 g. The adsorption model was consistent with pseudo-second-order kinetic and Freundlich isotherm model.
