Abstract: A novel liquid membrane system,denoted as strip dispersion hybrid liquid membrane(SDHLM),containing N₉₀₂ in kerosene as carrier,was studied as the function of dodecanol concentration,pH in feed phase,volume ratio between stripping solution and organic phase,and circulating flux of feed phase or strip dispersion phase.Solvent extraction verified that 1 mol of Cu²⁺ ions reacted with 2 mol of carrier and formed 1 mol of the Cu(Ⅱ)-carrier complex.The experiments showed that Cu(Ⅱ) could be efficiently transported into the stripping solution by SDHLM.When pH=2 in the feed phase,the recovery of copper(Ⅱ) in the stripping phase was 93.6%,while iron(Ⅲ) was 1.83% for Cu²⁺/Fe³⁺=1.The recovery of copper(Ⅱ) in the stripping) phase was 89.8%,while zinc(Ⅱ) was 1.38% for Cu²⁺/Zn²⁺=1 after transport for 4 h.When the concentrations of Cu²⁺,Fe³⁺,Co²⁺,Ni²⁺ and Zn²⁺ in the feed phase(pH=1.5) were 4.52,5.07,0.442,35.7 and 1.24 g/L,respectively,the recovery of Cu²⁺ in the stripping phase was 81.5%,while other metal ions were below 2.10% after the transport for 6 h.Separation experiments indicated that N₉₀₂ was an excellent extractant for Cu(Ⅱ).SDHLM has several advantages over SLM and ELM:increased membrane stability,improved flux,improved recovery of target species concentration,no usage of high active surfactant and demulsification) device,and reduced cost.
