目前,检测水中对硫磷的方法有酶抑制法,紫外分光光度法,偶氮染料法和靛酚法。但这些方法操作繁杂,为了适应基层卫生人员的检测需要,我们研究了一种测定水中对硫磷的比色法—硝酸亚汞试剂法。该法快速、准确、重现性好,如在水样中加入 At present, the method of detecting parathion in water is enzyme inhibition method, ultraviolet spectrophotometry, azo dye method and indophenol method. However, due to the complicated operation of these methods, in order to meet the testing needs of grass-roots health workers, we have studied a method for the determination of parathion in water-the mercury nitrate reagent method. The method is fast, accurate and reproducible, such as adding water samples
