亚麻对染料甲基紫吸附的响应面法分析

摘要

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 modifica-tion 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 modi-fication 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 .%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%.
