目前对矿石和一些其它材料中铀的测定,应用最广和最主要的方法要算容量法。铀的容量法主要是利用它的氧化还原反应。苏联科学家斯罗科姆斯基指出,在硫酸溶液中,V~(+5)/V~(+4)电位随着酸浓度增高而急剧增长,这就发展了铀的氧化还原滴定法。已经在实际生产中广泛应用的有磷酸盐-钒酸盐容量法,即伏尔科夫法,就是在这个基础上发展起来的。这个方 At present, the determination of uranium in ores and some other materials is the most widely used and the most important method to calculate the volumetric method. The volumetric method of uranium mainly uses its redox reaction. Soviet scientist 斯罗科姆斯基 pointed out that in the sulfuric acid solution, V ~ (+5) / V ~ (+4) potential increases sharply with increasing acid concentration, which developed the uranium redox titration. It has been based on the extensive use of the phosphate-vanadate capacity method, the Volkov method, that has been widely used in actual production. This side
