摘要

采用荧光免疫法原位测定地表水中2,4-二氯苯氧乙酸(2,4-D),方法在7.2μg/L～211.7μg/L范围内线性良好,最低检出限为2.6 μg/L.对空白水、长江水和湖泊水样品做2,4-D的4个质量浓度水平的加标回收试验,7次测定结果的RSD为3.9％～5.8％,加标回收率为85.9％～106％.用该方法与国标法同时测定黄石市内某长江水源地和某湖泊水中的2,4-D,结果无明显差异.

Abstract

In this study,2,4-Dichlorphenoxyacetic acid(2,4-D)in surface water was determined in suit by fluorescence immunoassay.The method had good linearity in the range of 7.2 μg/L to 211.7 μg/L.The detection limit was 2.6 μg/L.The spiked recoveries on blank and practical samples from Yangtze River and a lake at four mass concentration levels of 2,4-D were from 85.9％to 106％,and the RSDs of seven measurements were from 3.9％to 5.8％.There was no significant difference between the results by this method and the national standard method in determining 2,4-D in water from Yangtze River water source and a lake in Huangshi.
