摘　　要：准确分析浓海水中溴离子的浓度具有现实意义。系统介绍现今常用的几种分析方法,并分别探讨其各自的优缺点,以供在不同的条件和要求下选择适宜的分析方法。这些分析方法主要有:甲基橙目视比色法,离子选择性电极法,紫外可见分光光度法以及离子色谱法。目前只单纯使用以上分析方法,难以实现高标准的精确度和准确度,因此对浓海水的预处理也相应做了探讨。It has realistic meaning to accurately analyze the concentration of bromine ion in thick seawater.Several current analysis methods were introduced systematically,and their advantages and disadvantages were discussed respectively.Appropriate analysis method was choosed under different conditions and requirements.They included methyl orange visual colorimetric method and ion selective electrode method,ultraviolet spectrophotometer and ion chromatography.At present it was difficult to achieve high standards analysis with accuracy and precision by these methods simply,so the pretreatment of thick seawater were discussed correspondingly.
