摘要
本文对水样中的塔崩及其降解产物磷酸乙酯的提取方法进行了研究, 试验了不同的萃取剂及萃取时溶液的pH值.优化了萃取条件. 在pH=9时.二氯甲烷萃取塔崩的回收率较高.三次测定的变异系数小于3.0%. 用气相色谱-质谱(El方式)法测定了水样中的塔崩和磷酸乙酯.
The extraction method of tabun and its degradation product ethyl phosphate in polluted water is studied. The extractive conditions are optimized. High recoveries of tabun are achieved with dichloromethane as an extractant at pH 9. Coefficient of variation is less then 3.0%. Identification and determination of tabun and ethyl phosphate with gas chromatography-mass spectrometry is presented.
