【摘要】 本文对P507（2-乙基已基膦酸单酯）从盐酸介质中萃取铑的可能性作了研究,在适宜的条件下，氨化后的P507对铑的水合阳离子萃取，萃取率可达99％以上，反萃取率可达99．9％以上。更多还原

【Abstract】 This paper explores the feasibility of extraction of precious metal rhodium from chorhydric acid medium with mono-(2-ethylhexyl) 2-ethylhexyl phosphonate (P507). The experimental results confirmed that under suitable conditions the percentage extraction of hydrated cation of rhodium can reaJch above 99% and the percentage back extraction above 99.9%.更多还原
