研究从硝酸、硫酸和盐酸介质中用异戊醇萃取Re(Ⅶ)的过程,探讨了酸浓度和萃取剂用量对萃取率的影响.紫外-可见光谱证实了异戊醇萃取Re(Ⅶ)为离子缔合体系的阴离子交换反应.用同位素稀释法结合电感耦合等离子体质谱仪对黄铁矿、黄铜矿、磁铁矿和橄辉岩等地质样品中的痕量Re进行了准确测定.以橄榄岩国际标样(CCRMP,WPR-1)为监控样品,5次重复分析的平均结果(10.67 ng/g)与文献报道的分析结果(10.83 ng/g)一致.对黄铜矿单矿物样品中的Re进行分析,5次重复分析的相对标准偏差为1.03%. |

Extraction process of rhenium (Ⅶ) from the media of nitric, sulfuric and hydrochloric acids using isoamylol was studied. Effect of types and concentrations of acids, and volume of extraction reagent on extraction yield of rhenium was discussed. The extraction mechanism of rhenium(Ⅶ) was proved to be an anion exchange reaction by UV - Vis spectra. A method for the determination of trace rhenium in geological samples, such as pyrite, chalcopyrite, magnetite and rock, using isotope dilution - inductive coupled plasma mass spectrometry was developed. This method was verified by analyzing the international reference material ( CCRMP, WPR-1 ) and the analysis results were in good agreement with the value reported by Meisel and Moser. RSD ( n = 5) for Re content in chalcopyrite sample was 1. 03% . |
