摘要: 测定了 PbO_2/Ti 电极在10%海水、天然海水、0.5NNa_2SO_4和5MNaCl 溶液中,温度25℃时的阳极极化曲线。在高电流密度范围内,它比 Pt/Ti 电极具有较低的氯和氧的过电位。该电极在上述介质中的消耗率比 Pt/Ti 阳极大,但远小于 Pb～2%Ag 阳极。这种电极已应用于阴极保护系统和次氯酸钠发生器中。

Abstract：The anodic polarization curves of PbO_2/Ti electrode in 10% diluted sea water,natural sea water,0.5N Na_2SO_4 and 5M NaCl solutions at 25℃ have been measured.The chloride and oxygen overvoltages of PbO_2/Ti electrode are lower than those of Pt/Ti electrode at high current density region. Corrosion rates at given current density are determined by the weight loss method during electrolysis in the above mentioned solutions.The results have shown that corrosion rates of PbO_2/Ti anode are greater than those of Pt/Ti anode,but they are far smaller than those of Pb-2%Ag anode. PbO_2/Ti electrode has been used successfully in cathodic protection sys- tem and in the reacting vessel for the production of sodium hypochlorite.
