Abstract

A titrimetric method for determination of sulfide and of sulphur in steels with chloranilic acid by biamperometric and automatic potentiometric end-point detection is described. The construction of the sensor for potentiometric indication is also described. The results obtained agree with those of the iodine-thiosulfate method and with the certified values for the steels.

摘要

本文描述了一种通过双安培和自动电位滴定终点检测，用氯冉酸测定钢中硫化物和硫的滴定法。还介绍了电位指示传感器的构造。所得结果与碘-硫代硫酸盐法的结果以及钢的认证值相符。
