摘要
研究后交联反应前后氯甲基化聚苯乙烯交联微球对水中壬基酚聚氧乙烯醚(NP10EO)的吸附.结果表明,后交联反应能显著改善氯甲基化聚苯乙烯交联微球对NP10EO的吸附性能.两种吸附剂的吸附行为均不受溶液初始pH值的影响.吸附动力学结果显示,NP10EO在后交联反应前后氯甲基化聚苯乙烯交联微球上的吸附符合二级动力学.
The adsorption of NP10EO onto chloromethylated polymer and postcrosslinked polymer was investigated. Results showed that postcrosslinking of chloromethylated polymer led to an enhanced adsorption capacity of NP10EO. NP10EO adsorption was not affected by the initial pH values of the solutions. The kinetics of NP10EO adsorption onto the chloromethylated polymer and postcrosslinked polymer could be well described by second order kinetics.
