| 中文摘要: |
| 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72μg/L～2117μg/L范围内线性良好，最低检出限为26μg/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39%～58%，加标回收率为859%～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。 |
| 英文摘要: |
| 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 26 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. |
