原盐中溴含量的检测方法

Detection methods of bromine content in crude salt

原盐中溴含量对后续下游产品质量的影响较大,须要准确测量。阐述了原盐中溴含量的3种检测方法——离子色谱法、离子电极法、分光光度比色法,并通过选取有代表性的样品对这3种检测方法进行了比较和探讨,结果显示这3种检测方法均可对原盐中溴含量进行准确定量。

The bromine content in crude salt influenced greatly the quality of downstream products and thus needed detecting accurately. Three methods of detecting bromine content in crude salt were introduced, i. e. ion chromatography, ion selective electrode, and spectrophotometic colorimetry. The three methods were compared and discussed through detection of representative samples. The results showed the three methods accurately determined bromine content in crude salt.
