用硫酸钡重量法测定硫,精度较高,是公认的一种标准经典方法.但该法操作手续繁杂,耗电量大,费时间.碘量法间接测定硫同样手续繁琐,很少为人采用.近年来,用燃烧法测定硫虽逐渐有所流行,但该法对零星试料的测定也不合算,费时费电,而且操作者经验不多时难于掌握.为此,我们本着寻找一种多快好省的分析方法的精神,在队领导的支持和帮助下,经多次试验,试成了硫的容量测定方法,现简介如下.
The barium sulfate gravimetric method for the determination of sulfur with high accuracy is a well-established standard classical method, but the method is complicated and consumes a lot of power and takes time.Individual method for indirect determination of sulfur is cumbersome and rarely used In recent years, the determination of sulfur combustion method has gradually become popular, but the method of sporadic determination of the sample is not cost-effective, time-consuming electricity, and the operator with little experience difficult to grasp.To this end, we are looking for a The spirit of the method of analysis of the more prosperous province, with the support and help of the team leader, after several tests, tried to determine the sulfur capacity, are summarized below.
