在硫酸钡定硫法中,关于铜和锌离子的影响,文献中的记载有的是没有数据(1,2),有的仅有零星的几个数据(3,4b,5,6),或则虽有数据而所用的情况和实际分析的情况不尽相同(7,8).

The effects of copper and zinc ions upon the precipitation of barium sulphate have been noted for a long time.However,the results published were either not systematic(3,4b,5,6) or obtained under conditions apart from usual analytical practice(7,8).
