摘要
实验以丙烯酸丁酯和苯乙烯为单体 ,过氧化苯甲酰为引发剂 ,醋酸丁酯和甲苯作混合溶剂 ,溶剂用量与单体混合物的体积相同。采用溶液聚合的方法合成了一种新型固相微萃取吸附质 (苯乙烯 -丙烯酸丁酯共聚物 ) ,研究了此聚合物作为固相微萃取吸附质的性能。用顶空萃取法对水中低级芳烃化合物进行了萃取实验 ,考察了此高聚物涂层的热稳定性及单体比例与萃取率的关系。将自制涂层与PDMS涂层对低级芳烃化合物萃取量进行了比较 ,反映了苯乙烯 丙烯酸丁酯聚合物涂层的特点。
A new type of solid-phase micro extraction (SPME) adsorbent of phenyletylene-butyl acrylate copplymer was synthesized by using butyl acrylate and phenylethylene as monomers, benzoyl peroxide as an evocator, and N-butyl acetate anad methylbenzene as a mixed solvent. Behaviours of the polymer as SPME adsorbent were studied. Thermal stability of the polymer coating and the effect of monomer ratio to extraction rate were investigated.
