摘要
通过对原国家标准 GB1601-79(83)农药氢离子浓度的测定方法,以及 CIPACMT75 pH 值的测定方法的研究比较,建立了一种适用于农药原药、粉剂、可湿性粉剂、乳油等的水分散液(或水溶液)pH 值测定的新方法,即新的国家标准方法。新法等效采用了 CIPAC MT75 pH 值的测定方法,使农药 pH 值的测定更加准确合理,并可在国际范围内通用。
Refer to CIPAC MT 75 determintion of pH values,a new method, which can be applied to the pH value determination of aqueous dispersions or liquor of technical products,dust,wettable powder and emulsifiable concentra- te etc.,is introduced in this paper.It makes the pH value detemination in pesticides get accurate and reasonable,and the new method can be widely used in all over the world.
