A fiber coated with fullerene by solgel technique was used to determine the stripped phthalic diesters in polyvinyl chloride (PVC) toys dipped in simulated saliva by solidphase microextractiongas chromatography.
采用以溶胶 凝胶技术涂渍的富勒烯固相微萃取纤维头,利用顶空固相微萃取/气相色谱法对聚氯乙烯(PVC)塑料玩具在模拟人体唾液浸泡液中邻苯二甲酸二酯类化合物的溶出量进行了测定,并对模拟人体唾液中5种邻苯二甲酸二酯类增塑剂的固相微萃取时间、萃取温度、盐效应、热解吸时间、振荡速度等条件进行优化,研究了PVC塑料玩具在模拟人体唾液中的浸泡条件对增塑剂溶出量的影响。
