摘要
Extraction behaviour of Cadmiun（Ⅱ） with a new trilon N,N′-di（dodecyl）ethylenediamien-di-acetic acid （H2R2Y） in chloroform was investigated.Complex ratio between H2R2Y and Cd2+ 1∶1 was substantiationed by conductance and mole ratio method.The influence of acidity,concentration of H2R2Y,phase-radio and temperature of extraction reaction was studied.The results indicated that:percentage extraction of Cd（Ⅱ） increased with the increase of the concentration of H2R2Y and the distribution ratio lgD decreased linearly with the increase of temperature.ΔHo=-7.254KJ·mol-1 for the extraction reaction.
Extraction behaviour of Cadmiun(Ⅱ) with a new trilon N,N′-di(dodecyl)ethylenediamien-di-acetic acid (H_2R_2Y) in chloroform was investigated.Complex ratio between H_2R_2Y and Cd^(2+) 1∶1 was substantiationed by conductance and mole ratio method.The influence of acidity,concentration of H_2R_2Y,phase-radio and temperature of extraction reaction was studied.The results indicated that:percentage extraction of Cd(Ⅱ) increased with the increase of the concentration of H_2R_2Y and the distribution ratio lgD decreased linearly with the increase of temperature.ΔH^o=-7.254KJ·mol^(-1) for the extraction reaction.
