摘要
以1,2-二氯乙烷为成孔剂,偶氮二异丁腈为引发剂,聚乙烯醇为稳定剂,4-乙烯基吡啶(4-VP)为功能单体,与二乙烯基苯共聚合成4-乙烯基吡啶-二乙烯基苯共聚物(4-VP-DVB),研究4-VP用量对4-VP-DVB物化参数及对煤化工废水中苯酚吸附性能的影响.结果表明:4-VP用量为5%～10%(w)时,4-VP-DVB的比表面积相对较大,且平均孔径较小,孔体积较大,对煤化工废水中苯酚的吸附性能较优,对苯酚的静态吸附动力学更符合准二级吸附动力学方程,且物理吸附是主要的驱动力.
Abstract
1,2-Dichloroethane was used as pore forming agent,azobisisobutyronitrile as initiator,polyvinyl alcohol as stabilizer,and 4-vinylpyridine(4-VP)as functional monomer to copolymerize with divinylbenzene to synthesize 4-vinylpyridine divinylbenzene copolymer(4-VP-DVB).The effect of the amount of 4-VP on physicochemical parameters of 4-VP-DVB and its adsorption performance to phenol in coal chemical wastewater were investigated.The results show that when the mass fraction of 4-VP is from 5%to 10%,the specific surface area of 4-VP-DVB is relatively large,whose average pore diameter is small and whose pore volume is high.Its adsorption performance to phenol in coal chemical wastewater is better,and its static adsorption kinetics to phenol is more in line with the pseudo second order adsorption kinetics equation in which physical adsorption is the main driving force.
