用磺基水杨酸和硫酸为掺杂剂,过硫酸铵为氧化剂,合成了一种高电导率聚苯胺粉末,并压制成聚苯胺阳极。采用FTIR和DSC/TGA对聚苯胺的结构和热稳定性进行分析,同时也采用加速电解寿命测试和电化学阻抗技术,研究了聚苯胺阳极的电化学性能和该电极在硫酸中的使用寿命。结果表明,在电解过程中槽电压从不稳定-稳定-快速增大的变化过程,电化学行为变化也比较明显。把该电极用于处理含酚废水和铅电极进行对比表明,节电率达34%,转化率达96.8%,是一种优良的电化学催化剂。
Using sulfosalicylic acid and sulfuric acid as dopants and ammonium persulfate as oxidant, a high conductivity polyaniline powder was synthesized and pressed into polyaniline anode. The structure and thermal stability of polyaniline were analyzed by FTIR and DSC / TGA. The electrochemical performance of polyaniline anode and the service life of the electrode in sulfuric acid were also investigated by accelerated electrolytic life test and electrochemical impedance spectroscopy. The results show that in the process of electrolysis, the cell voltage changes from unstable to steady to rapid increasing, and the electrochemical behavior changes obviously. The electrode used in the treatment of phenol-containing wastewater and lead electrode for comparison shows that the saving rate of 34%, the conversion rate of 96.8%, is an excellent electrochemical catalyst.
