摘要: This study covers the transportation of Cu (Ⅱ) ions by multi-dropped liquid membrane (MDLM) system and tri-noctylamine (TNOA) as carrier in kerosene.Batch experiments are held to obtain optimum conditions for the transportation of Cu (Ⅱ) ions such as volume of donor,organic,and acceptor phase 100 ml,pH of donor phase 9.00,temperature 298.15 K,concentration of H2SO4 in acceptor phase 1.00 mol·L-1,concentration of TNOA in organic phase 5.00×10-3 mol·L-1 and rate of peristaltic pump 50 ml·min-1.Optimum circumstances of this extraction are as follows:pH of donor phase is 9.00,concentration of TNOA is 5.00×10-3 mol·L-1,1.00 mol·L-1 H2SO4 as acceptor phase,and flux rate is 50 ml·min-1.Cu (Ⅱ) ion transportation is consecutive first order irreversible reaction.Activation energy is found as 5.22 kcal·mol-1(21.82 kJ·mol-1),this process is called as diffusion controlled system.Selective transportation of Cu (Ⅱ) ions with alkaline,alkaline earth,and different heavy metal ions at optimum conditions of single Cu (Ⅱ) extraction was conducted.According to the selective transportation Cu (Ⅱ) ions with alkaline and alkaline earth metal ions,Na+,K+,and Ba2+ ions are not detected in the acceptor phase,but 12.00% of Ca2+ ions is transported from donor phase to acceptor phase.At the end of the simultaneous extraction of Zn (Ⅱ),Fe (Ⅲ),and Mo (VI) with Cu (Ⅱ) ions,2.20% of Mo (VI),0.80% of Fe (Ⅲ) and 3.60% of Zn (Ⅱ) are detected in the acceptor phase.
