摘要
本文报道了利用正交设计实验方法,考察了诸方面因素对含钼鸽体系中钼钨的定量分离与测定的影响,提出了分离的最佳条件为:酒石酸与鸽酸钠之摩尔比为20—30,1:3H_2SO_46—8ml,通 H_2S25—30分钟。经实验证明,这种方法,结果合理,并且容易掌握和应用。
In this paper,a experimental method using quadrature design is reported.The effective factors on the quantitative separation and determination of molybdenum and tungsten in system containing molybdenum and tungsten are investigated. The optimum conditions of separation are found as follows:the molar ratio of etartaric acid to Na_2WO_4 is 20—30;1:3H_2SO_4(v/v)added is 6—8 ml;the time of aerating H_2S gas is 25—30 min.The experimental results show that this method is reasonable and easy application.
