摘要
酚类化合物广泛应用于农药、塑料、药物、造纸、纺织品以及皮革等工业生产,通过直接或间接途径释放到环境中。近年来,环境水体、土壤等基质中均检测出浓度低于μg L~(-1)水平的酚类化合物。其中,多种酚类化合物被EPA列为优先控制污染物。本研究采用沉淀聚合技术合成2,4,6-三氯苯酚(2,4,6-TCP)印迹聚合物,并将其作为分散固相萃取吸附剂,结合毛细管电泳技术分析水样中的7种酚类物质(苯酚、2-氯酚、4-氯酚、2,4-二氯酚、2,6-二氯酚、2,4,6-三氯酚和五氯酚)。对影响分离效率的毛细管电泳条件和影响萃取效率的分散固相萃取条件进行优化,可在13.5 min内实现7种物质的基线分离,线性范围分别为2-200μg L~(-1)(苯酚、2,4-DCP和2,6-DCP)、2-300μg L~(-1)(4-CP和2-CP)、1.5-150μg L~(-1)(PCP)和2-400μg L~(-1)(2,4,6-TCP)。该方法应用于自来水、湖水、海水及制革废水中酚类物质的萃取和分析,回收率范围为73.20-106.7%。
A simple and sensitive method for the simultaneous determination of seven phenols in water samples was developed by dispersive solid phase extraction(DSPE) coupled with capillary electrophoresis(CE).Molecularly imprinted polymers prepared by precipitation polymerization with 2,4,6-TCP as template were used as DSPE sorbents to selectively adsorb phenolic compounds.Various parameters affecting the extraction efficiency were evaluated and excellent CE separation was achieved within 13.5 min.The developed MIPs-DSPE-CE method was also applied to determine phenols in lake,tap,seawater and tannery wastewater.
