摘要
将不同的稳定剂添加到亚氯酸钠溶液中,配得7个样品,然后跟踪测量7个样品中的氯气、二氧化氯和亚氯酸盐含量以评价其稳定性。实验结果发现,实验32天后,样品6的剩余ClO2-含量最高,为初始值的59.79%,说明样品6的稳定性表现最佳,即8-羧基喹啉、二乙烯三胺五甲叉膦酸和过氧化氢的加入能有效增加亚氯酸钠溶液的稳定性,为配制稳定性亚氯酸钠溶液提供了一种良好的选择和参考。
Seven samples were preparated by adding different stabilizers into sodium chlorite solution, and the sta-bility of the 7 samples were evaluated by measuring the content of chlorine, chlorine dioxide and chlorite regularly. From datas, it is known that 6th sample is the most stable solution, remaiding 59. 79% ClO2^-finally. It is said that adding 8-carboxyl quinoline, DTPMPA and H2 O2 into the sodium chlorite solution can improve the stability of sodium chlorite ef-fectively. And this research provids a favorable choice to make up stabilized sodium chlorite solution.
