摘要
研究了协同流动载体(HEHEHP+TOA)表面活性剂(ENJ-3029)、溶剂(煤油)和内相(1.2%草酸溶液)等高效液膜体系,对分离富集微量铪的影响。确定了HEHEHP-TOA-ENJ-3029-煤油-草酸溶液体系的最佳组成、最适宜的实验条件。实验表明,只有HfO2+能从常见的金属离子(如Zr4+、Fe3+、Al3+、Ti4+、SiO2-3等)中得到满意的分离富集。富集后的铪用偶氮胂Ⅲ法分光光度计测定之。该法已用于富集和测定锆英石矿、氧化锆和锆铁合金中的微量铪,结果十分满意。
Effect of high efficacy liquid film system as cooradinated flowing carrier(HEHEHP+TOA), surface active agent (ENJ-3029), solvent(kerosence) and internal phare(1. 2 % H2C2O4 solution) on the sepeting conentrated trace hafnium has been investigated. The optimum compeition of HEHEHP-TOA- ENJ -3029- kerosene-H2C2O4 soution and the most suitable testing condition have been fixed. The results indicate that only Hny2 2+ can be separted for common metal ion such as Zr4+, Fe3+, Al3+, Ti4+ and so on. The concentrated hafnium was determined by azoarsine Ⅲ spectrophoto-meter.
