摘要
研究了海水中的SO42-、OH-和CO32-/HCO3-等阴离子含量对铱钽锡（Ti/Ir O2-Ta2O5-Sn O2）阳极电流效率的影响,并通过极化曲线、循环伏安分析了不同阴离子的作用机制。结果表明：SO42-对电流效率基本没有影响。OH-对阳极的析氯电流效率有一定的影响,阳极电流效率随OH-浓度的升高而略微下降,OH-浓度达到0.1 mol/L时,电流效率下降约2%。CO32-/HCO3-对阳极的电流效率有较大的影响。HCO3-达到0.1 mol/L时,电流效率下降约10%。CO32-达到0.1mol/L时,电流效率下降约40%。
The effect of anions including SO42-,OH-,HCO3-and CO32-in seawater on the current efficiency of anode of Ti/Ir O2-Ta2O5-Sn O2was studied.The effect mechani s m of different anions was analyzed by polarization curves and cyclic voltammetry techniques.The results show that SO42-has no effect on the current efficiency.OH-has trifling impact on the current efficiency.With the increase of OH-concentration,the current efficiency decreases a little.When OH-concentration reaches 0.1 mol/L,the current efficiency decreases about 2%.CO32-/HCO3-has great negative effects on the current efficiency of anode.If the HCO3-concentration reaches 0.1mol/L,the current efficiency decreases about 10%.When CO32-concentration reaches 0.1mol/L,the current efficiency decreases about 40%.
