摘要
采用气提-捕集气相色谱法对水中苯、甲苯、二甲苯、乙苯、异丙苯、苯乙烯和正丙苯等芳烃的回收率进行了研究.对自来水、江河水、污水及工业废水等多种水体中的该类物质进行了测定.使用5ml气提装置时,不同芳烃的最低检测浓度为0.2—0.4ppb.
The recovery of benzene, toluene, cthylbenzenc, o-xylene, m-xylene, p-xylene, cumene, slyrene and n-propylbcnzene in ater samples was studied by a purge and trap gas chromatographic method. These compounds in tap water, river water and v astewater were determined. With a 5ml purge device, the minimum detection limit concentrations for different aromatics were found to be in the range of 0.2 to 0.4 ppb.
