| 摘 要： | 在含3 mol/L钒离子的钒硫酸溶液中分别加入碱金属硫酸盐、碱金属草酸盐以及有机物脲和甘油等添加剂,提高了电解液稳定性。探讨了添加剂影响钒硫酸溶液稳定性的机理。对含添加剂的钒硫酸溶液的电导率的测定表明,适量添加剂不会降低溶液的电导率,有些甚至稍有提高。对含有添加剂的钒硫酸溶液进行了循环伏安试验,表明添加剂的加入不会对钒硫酸溶液的电极反应产生不利影响。

| Abstract: | The solubility and stability of vanadium ion in vanadium sulfate solutions were improved by adding alkali metal sulfate, alkali metal oxalate, urea and glycerin respectively. The stability mechanism of the electrolyte with the additives was discussed. The conductivity of electrolytes with the additives and without additives were measured. The results show that the conductivity of electrolyte with additive less than 3% is hardly changed compared with the electrolyte without additives. The cyclic voltammogram investigation displays no adverse effect of the additives on the vanadium redox reaction in vanadium sulfate solution. |
