Method for detecting stability of sodium gold sulfite solution

A method for detecting the stability of a sodium gold sulfite solution comprises the following steps: adding a certain amount of the sodium gold sulfite solution into an alkali solution with required concentration, then adding a hydrogen peroxide solution, and comprehensively judging the stability of the sodium gold sulfite solution according to the color change time of the mixed solution and the gold foil precipitation time. The essence of the method is as follows: firstly, various ligands in the sodium gold sulfite solution are destroyed by utilizing the oxidability of the hydrogen peroxide, then gold in the solution is reduced by utilizing the reducibility of the hydrogen peroxide, and finally, the stability of the sodium gold sulfite solution is determined according to the length of two reaction times. The method has the advantages of high measuring speed, stable effect, simplicity in operation and the like. 一种亚硫酸金钠溶液稳定性的检测方法，将一定量的亚硫酸金钠溶液加入到要求浓度的碱溶液中，然后加入双氧水溶液，通过混合溶液变色时间和析出金箔时间综合判断该亚硫酸金钠溶液的稳定性。本发明的实质是首先利用
