| 摘 要： | 在印刷电路板酸性蚀刻废液中选用Ir系和Ru系电极作阳极,通过稳态动电位扫描和循环伏安扫描,对电极表面发生析氯和电积铜反应过程动力学进行了研究.在0.5 mol/L H_2SO_4溶液中及20kA/m~2电流密度下,Ir系钛阳极的强化使用寿命为Ru系钛阳极的20倍.Ir系钛阳极的析氯电位比Ru系钛阳极高,两种电极的析氯反应都属于不可逆反应.

| Abstract: | The electrodes in the system Ru and system Ir have been selected as anode used in the spent acidic etchant for printed circuit board.The electrode process kinetics of chlorine evolution and copper electrolytic deposition on the electrode surface has been investigated by the steady-state potentiodynamic scanning and cyclic voltammetry.The accelerating service life of electrode in the system Ir is twenty times as long as that in the system Ru in the 0.5 mol/L sulfuric acid solution under the current density o... |
