| Abstract: | Didecylphosphinic acid has been synthesized by the reaction of low-cost industrial by-product mixture-decene with sodium hypophosphite under normal pressure.The isolated yied was up to 99.5% and the purity is 98%.Further extraction study of Co2＋and Ni2＋ showed that the selectivity is higher than the wide used Cyanex272 while the extraction rate and washing rate are comparable to Cyanex272.Futhermore,didecylphosphinic acid can been used in low pH to directly extract metal ions from leach liquor. |
