采用金属铝置换回收铜(英文)

研究了采用球形铝金属粒子从硫酸铜水溶液中置换铜离子。考察了各实验参数初始铜离子浓度、反应温度、搅拌速度、溶液pH值等对铜置换反应的影响。结果表明,反应速率随着铜离子浓度、反应温度和搅拌速度的增加及pH的降低而提高。置换反应遵循一级动力学方程,其控制步骤为扩散控制。

Recovering of copper with metallic aluminum

The cementation of copper ions from aqueous copper sulfate solutions by using spherical aluminum metal particles was examined. The effects of the experimental parameters on copper cementation were investigated and evaluated. Reaction rate increases with increasing copper concentration, reaction temperature, stirring speed and decreasing pH. It was observed that the reaction follows the first-order kinetics, and progresses according to the diffusion controlling step.
