浅谈硫酸根的重量法和容量法测定

Brief Discussion on the Determination of Sulfate Radicals with Gravimetric Method and Volumetric Method

硫酸根的重量法和容量法测定各有所长,当硫酸根小于1.00%其容量法测定可以替代重量法,只要相应条件控制好,一样可以获得精确的结果。

Gravimetric method and volumetric method of sulfate radicals have their own merits and demerits.When sulfate radical is under 1.00%,volumetric method can replace gravimetric method.Accurate results can be obtained as long as relevant condition is well controlled .
