中文摘要 | the mass transfer behaviors of cd(ii), fe(iii), zn(ii), and eu(iii) in sulfuric acid solution using microporous hollow fiber membrane (hfm) containing bis(2,4,4-trimethylpentyl)monothiophosphinic acid (commercial name cyanex302) were investigated in this paper. the experimental results showed that the values of the mass transfer coefficients (k-w) decreased with an increase of h+ concentration and increased with an increase of extractant cyanex302 concentration. the mass transfer resistance of eu3+ was the largest because k-w value of eu3+ was the smallest. the order of mass transfer rate of metal ions at low ph was cd > zn > fe > eu. mixtures of zn2+ and eu3+ or of zn2+ and cd2+ were well separated in a counter-current circulation experiment using two modules connected in series at different initial acidity and concentration ratio. these results indicate that a hollow fiber membrane extractor is capable of separating the mixture compounds by controlling the acidity of the aqueous solution and by exploiting different mass transfer kinetics. the interfacial activity of cyanex302 in sulfuric acid solution was measured and interfacial parameters were obtained according to gibbs adsorption equation. |
