【摘要】 用悬汞电极测定了Ａｓ（Ⅲ）在不同条件下氯化物溶液中的阴极极化曲线，实验结果表明，Ａｓ（Ⅲ）的电化学行为强烈地受溶液中Ｎ＋，Ｃｌ－及Ａｓ（Ⅲ）浓度的影响，不同的条件下，可表现出不同阴极极化行为。更多还原

【Abstract】 Cathodic polarization curves of As(Ⅲ)in acidic chloride solution were taken by a hang-ing drop mercury electrode. The electrochemical behaviors of As(Ⅲ)are influenced stronglyby the concentrations of H+ ,Cl-and As(Ⅲ).Different cathodic processes under differentconditions have been shown in the paper.更多还原
