, China 3) Chinese Academy of Engineering, Beijing 100038, China摘 要:The electrochemical process of galena in a pH 12.8 buffer solution was investigated using chronoamperometry and chronopotentiometry. To establish kinetic parameters on the surface of galena in the diethyldithiocarbamate solution, the exchange current density and the dependence of current......
as the concentration of ammonium sulphate increases (Fig. 2(b)). This may be attributed to two reasons. One is that ammonium sulphate forms a buffer solution with ammonia and pH of the solution is kept...J. Cent. South Univ.
