英文摘要: Abstract(#br)The solvent extraction and stripping of copper have been conducted in a Y-Y type microchannel reactor. The experimental results demonstrate that the Y-Y type microchannel reactor can be used for both Cu extraction and Cu stripping. The effects of residence time, aqueous phase pH, and concentration of extractant on the extent of extraction were investigated. The results indicated that the extent of extraction and the separation factor using a Y-Y type microchannel reactor are greater than those obtained with a conventional batch extraction. The maximum extraction of copper reached 86.02%. Also, the stripping reaction was studied with respect to Cu 2+ concentration in the loaded organic phase, H 2 SO 4 concentration, and the organic/aqueous phase ratio. The maximum stripping of...
