摘要
以漳州开发区污水处理厂活性污泥为原料,通过不同的预处理方法制成生物吸附剂。用分光光度法测量8种预处理后的活性污泥对结晶紫的吸附效果,并对影响吸附因素进行研究。实验结果表明,经过NaOH和H2O2预处理后的活性污泥对结晶紫具有较好的吸附效果,弱碱性条件可以增强吸附效果。
In this study,activated sludge was treated to biosorbent for crystal violet by different treatment means.The adsorption of crystal violet for 8 different pretreatment means was measured by spectrophotometry,and the factors affecting the adsorption were also studied.Experiment results proved that NaOH H2O2 pretreated sludge has the best adsorption for crystal violet.Uptake capacity was high in weak alkaline condition.
