摘要: 本文用萃取法测定了(Ⅰ)Y(Ⅲ)/0.5MNaClO4/PMTFP-C6H6和(Ⅱ)Y(Ⅲ)/0.5MNaClO4/PMTFP-TBP-C6H6及(Ⅲ)Y(Ⅲ)/0.5MNaClO4/PMTFP-TOPO-C6H6体系的萃取平衡常数和协苹平衡常数,结果如下: 体系(Ⅰ)的1gK30=-3.36;体系(Ⅱ)的1gK32=4.47; 体系(Ⅲ)的1gK31=6.65、1gK32=9.08。 |

Abstract: The extraction of yttrium(Ⅲ) from perchloric acid solutions into mixtures of l-phenyl-3-methyl-4-trifluoroacetyl-pyrazol-one-5 (PMTFP) and neutral organophosphorus extractants, e. g. tri-n-butylphosphate (TBP) or tri-n-octylphosphinoxide(TOPO), in benzene has been studied.The formula of the extracted species have been shown to be YA3 S and YA3 2S (where HA = PMTFP, S = TBP, TOPO), and their equilibrium constants have been calculated. It is found to be greater for such mixtures than the either component alone. |
