摘要
磷矿中氟、氯、碘的定量分析,通常采用分别取样,碱熔测定,手续比较麻烦。有人早已报导离子交换树脂可在水溶液中分解难溶块,文献介绍可以分解磷灰石,并用于测定氟。其后,则未见有实际应用的报导,我们在此基础上,详细地试验了用国产732型阳离子交换树脂分解磷矿的条件。试验证明,在分解样品后所得的溶液中,由于阳离子被分离除去,可以直接分取溶液采用一般方法测定氟、氯和碘。手续简便,效果较好。
The factors affecting dissociation of phosphate rocks in water with cation exchange resin (Model 732) was investigated, and a simple rapid procedure for simultaneous determination of fluorine, chlorine and iodine were discribed. The results were in good agreement with those obtained by the routine methods. The C. V. % of analytical results for fluorine, chlorine and iodine were 5,14 and4 respectively.
