本文叙述去氢抗坏血酸可以隐蔽锆与钍试剂的反应,并建议用于以钍试剂比色测定合锆溶液中的钍.最宜操作条件为酸度0.2-0.25N;加热时间一分半,钍试剂浓度为4毫克/50毫升.不同锆钍比例及不同去氢抗坏血酸量存在时均对钍的发色无影响.文中并叙述一快速测定独居石中钍的方法.
This article describes the dehydroascorbic acid can conceal the reaction of zirconium and thorium reagents, and is recommended for the determination of thorium zirconium solution thorium reagent colorimetric determination of the optimum operating conditions of acidity 0.2-0.25N; half a heating time, thorium reagent The concentration of 4 mg / 50 ml of different zirconium thorium ratio and the amount of different dehydroascorbic acid have no effect on the color of thorium hair color.This paper describes a rapid determination of monazochlor thorium method.
