摘要
应用已研制出的酶片和显色基质片快速测定水中有机磷和氨基甲酸酯农药. 这种方法能够在田间没有仪器的情况下检测农药的危险水平.对于大多数有机磷氨基甲酸酯农药,其检测灵敏度在見0.1—3.0ppm范围.方法具有快速、经济,容易在田间现场使用的特点。
A biochemical method for rapid detection of organophosphorus and carba-mate pesticides in water has been developed. The method is based on the observation of the color developed by adding to the water sample a kind of enzyme tablet, together with a colorforming substrate tablet. Qualitative identification and quantitative estimation are accompanished by comparing the color intensity with those developed for known pesticides of different levels. The sensitivity of the method is in the range of 0.1-3.0ppm for most organophosphorus and carbamate pesticides. The method needs no expensive apparatus; it is rapid and convenient, and can be used in the field.
