摘要
以氯甲基化聚苯乙烯树脂(氯球)为原料合成超高交联聚苯乙烯树脂JL,并采用水杨酸进行修饰,得到改性聚苯乙烯树脂JL-BHA,对JL-BHA的红外光谱进行分析,研究了JL-BHA投加量、温度以及重金属Cu2+初始浓度对重金属废水的吸附效能.结果表明:JL-BHA的合成是成功的,当JL-BHA的用量从0.01g增加至0.1g时,Cu2+的去除率先增加后稳定,Cu2+的吸附量逐渐降低,Cu2+去除率最高为84.58%.随着Cu2+初始浓度的增加,JL-BHA对Cu2+的吸附量也逐渐增加,但是对Cu2+的去除率却逐渐下降,而温度对Cu2+去除效果影响较小.
Abstract
The ultra-high crosslinked polystyrene resin JL was synthesized from chloromethylated polystyrene res-in(chlorine sphere)and modified with salicylic acid to obtain the modified polystyrene resin JL-BHA.The infra-red spectrum of JL-BHA was analyzed,and the adsorption efficiency of JL-BHA dosage,temperature,and initial concentration of heavy metal Cu2+on heavy metal wastewater was studied.The results showed that the synthesis of JL-BHA was successful.When the dosage of JL-BHA increased from 0.01 g to 0.1 g,the removal of Cu2+first increased and then stabilized,and the adsorption capacity of Cu2+gradually decreased.The highest removal rate of Cu2+was 84.58%.As the initial concentration of Cu2+increased,the adsorption capacity of JL-BHA for Cu2+also gradually increased,but the removal rate of Cu2+gradually decreased,and the effect of temperature on Cu2+re-moval was relatively small.
