英文摘要: Abstract(#br)Microfluidic solvent extraction of copper from sulfate solution containing Cu 2+ , Fe 3+ and Zn 2+ using DZ988N (a mixture of equal volumes of 5-nonylsalicylaldoxime and 2-hydroxy-5-nonyl-acetophenoneoxime) has been conducted for the first time using an interdigital micromixer with 30 channels of 40 μm width. Conventional batch extractions were carried out in parallel for comparison. Effects of the initial pH value of the aqueous phase, concentration of the extractant, and flow rate on the extraction efficiency of Cu 2+ have been studied including determination of separation factors ( β Cu / Fe and β Cu / Zn ). According to single factor experiments, the optimal extraction parameters were an initial pH value of 1.96, extractant concentration of 15% and an aqueous or organic...
