由茅草枯、2甲4氯和敌草隆混合配制而成的三元除草剂,是一种新型的内吸传导型混合除草剂,对防除杂草具有很好的效果。这种复合除草剂的分离分析方法比较困难,目前国内还没有报导,作者经过探索总结出如下的分离分析方法。茅草枯能溶解于硝酸汞缓冲溶液,利用这一特点可以首先把它分离出来,不溶于硝酸汞缓冲溶液部分则

The ternary herbicide, which is prepared from the mixture of thatch grass, 2 A 4 chloro and diuron, is a new type of mixed herbicide with internal absorption conduction and has good effect on controlling weeds. This compound herbicide separation and analysis methods more difficult, at present there is no report, the author summed up the following separation analysis method. Thatch can dissolve in mercury nitrate buffer solution, the use of this feature can be the first to separate it, do not dissolve in the part of the mercury nitrate buffer solution then
