对井盐卤水中锂含量(通常含量较微)的测定,一般使用的方法手续繁复,费时较多,不能满足当前工业的需要,所以必须找出一快速而简便的方法。由于卤水中含有大量钠盐,而一般在工业上常用的分析方法如某些重量法、以及利用过碘酸盐沉淀与高铁过碘酸盐沉淀的一些容量或比色测定法,在大量钠盐存在时,对锂的测定结果均有显著影响。因之锂与钠的分离为卤水中测定锂的关键。较早的文献中曾提 Lithium brine brine salt content (usually slightly) determination, the commonly used methods complicated procedures, more time and can not meet the needs of the current industry, it is necessary to find a quick and easy way. Because brines contain large amounts of sodium salts, the analytical methods commonly used in industry, such as some gravimetric methods, and some capacity or colorimetric assays that utilize the precipitation of iodate and the generation of hyperlipidemia in high iron, When present, the results of lithium measurement have a significant impact. Because of the separation of lithium and sodium as the key to determination of lithium in brine. Earlier references were mentioned
