摘要
本文提出了包括疏水吸附剂富集及气相色谱或液相色谱分析方法。报道了邻苯二甲酸酯在Amberlite XAD-2和SS401上的富集容量,研究了水样pH和流速对回收率的影响,GC采用填充柱或毛细柱,HPLC采用细径反相柱,适用于分析大分子量邻苯二甲酸酯。当取样量为10升时,本法的检测极限为ppb水平。
In this paper, GC or HPLC determination of trace phthalate esters that have been enrichedwith a hydrophobic sorbent was described. The enrichment capacities on Amberlite XAD-2 andSS-401 (a porous polymeric resin available in Chinese market) of some phthalate esters, the effectof pH, and the flow rate of sample have been studed. packed column or capillary FSOTcolumn was used for GC analysis while narrow reversed column that were especially suitablefor high molecular weight phthalate esters was used for HPLC analysis with detection limits ofppb level in 10 liters of samplo.
