| 摘 要： | 以环氧树脂基聚合物膜为萃取相,在电场作用下富集目标物,与高效液相色谱(HPLC)联用,应用于环境水样中硝基苯污染物的测定.考察了电压大小、萃取时间、洗脱时间、离子强度和溶液pH值对电增强萃取效率的影响.实验结果表明,环氧树脂基聚合物膜的萃取量与膜上所施加的控制电位相关,阴极极化时,膜对硝基苯的萃取量增大;在阳极极化时,膜萃取量减小.在电压为-0.3kV,硝基苯溶液pH=4的条件下,萃取20min,得到该方法的检出限为0.015μg·mL-1,在0.05～3.0μg·mL-1范围内具有良好的线性关系,可决系数为0.9929,变异系数小于5%.用上述方法分析鱼塘水,硝基苯3种不同加标水平的回收率为79.8%～108.2%.结果表明,该方法既可用于环境水样品中的硝基苯去除又可用于检测.
