摘要

采用循环伏安法研究草酸在 Pt 电极上的电化学行为，介绍以交流电解法破坏草酸，考察交流电周期、电源电压等条件对电解破坏草酸的影响。结果表明：草酸破坏率为99％时，交流电解的电流效率为恒流电解的7倍，电解速度是恒流电解的2．5倍；优化工艺条件下，草酸破坏速度很快。%The electrochemical behavior of oxalic acid at Pt electrode was investigated by cyclic voltammetry ,the alternating current electrolysis method was proposed to destroy oxalic acid .The influence of alternating current frequency ,supply voltage and other parameters on oxalic acid destruction speed was studied .The results show that current efficiency and destruction speed for oxalic acid of alternating current electrolysis method are 7 times and 2 .5 times over that of direct current electrolysis method .Under the optimal conditions ,more than 99 .6% of oxalic acid can be easily destroyed .
