氢氧化铁作为一种共沉淀剂已被用于富集及分离微量砷钒及其它痕迹元素.在高离子浓度的溶液中,以离子交换的方式用氢氧化铁共沉淀水体中痕迹元素的方法具有手续简便,不易玷污及分析精密度高的优点。本法研究了氢氧化铁共沉淀海水中钛及锰时的pH条件,载体用量,陈化条件、离子干扰情况及ICP光谱法测定条件选择等,从而制定了一种简便易行的测试方法。 Iron hydroxide as a coprecipitator has been used to enrich and separate traces of arsenic and vanadium and other trace elements in high ionic strength solution by ion exchange with iron hydroxide co-precipitation of trace elements in water With the simple procedure, not easily defiled and analysis of the advantages of high precision. This method was developed for the determination of titanium and manganese in ferric hydroxide in seawater when the pH conditions, the amount of carrier, aging conditions, ion interference conditions and ICP spectrometry to determine the conditions of choice, and thus developed a simple and easy test method.
