測定有机化合物中含硫量时,一般將有机物分解,使形成硫酸根,然后用重量法测定,但是这个方法費时很長,如果用濁度法則往往誤差很大。利用电流滴定法測定有机化合物中的硫是一个比較好的方法,既迅便又准确,既可用于常量,也可用于微量或半微量。用电流滴定法測定硫酸根,虽然早在二十年前即已由Majer提出,但是应用这个方法来作有机化合物中硫的定量分析,直到最近才引起人們的注意。1954年,Warshowsky及其合作者报导了用过氧化鈉彈燒法分解有机化合物,然后用电流滴定法測定生成的硫酸根。他們用 Determination of organic compounds sulfur content, the general decomposition of organic matter, the formation of sulfate, and then gravimetric determination, but this method takes a long time, if the law of turbidity is often a large error. The use of current titration of organic compounds in the determination of sulfur is a better method, both fast and accurate, both for constant, can also be used for trace or semi-trace. The use of current titration for the determination of sulfate, which has been proposed by Majer as early as twenty years ago, has been used until recently for the quantitative analysis of sulfur in organic compounds, until recently. In 1954 Warshowsky and his collaborators reported the decomposition of organic compounds by sodium peroxide bombardment and the generation of sulfate by current titration. They use
