摘　　要：应用线性电位扫描法研究了温度对Pb 1%Ce合金在 0 9V (vs .Hg/Hg2 SO4 电极 ) ,4 5mol·dm-3 H2 SO4 溶液 (2 83～ 32 3K)中阳极Pb (Ⅱ )膜的生长速率的影响。实验结果表明 ,铈的添加可适当提高Pb (Ⅱ )化合物生长过程的表观活化能。在温度为 2 83～ 2 93K时 ,铈对铅在硫酸溶液中的阳极腐蚀有一定的抑制作用。The growth rates of the anodic Pb(Ⅱ)films formed on Pb 1% Ce alloy at 0 9 V(vs.Hg/Hg 2SO 4)in 4 5 mol·dm -3 H 2SO 4 solution(283～323 K)were studied using the linear sweep voltammetry.The experimental results show that the addition of cerium to lead metal can slightly increase the apparent activation energy of the reaction for forming anodic Pb(Ⅱ)compound.Cerium can also inhibit the anodic corrosion of lead in sulfuric acid solution at temperature between 283 and 293 K?
