摘要
用稳态极化法研究了Ｃｕ—Ｎｉ合金阴极在对氨基苯酚（ＰＡＰ）电解过程中的有关性能。研究表明，在ＰＡＰ电合成体系中，不同Ｃｕ／Ｎｉ比的合金阴极具有不同的交换电流密度ｉ°，且随着镀液中Ｃｕ（Ⅱ）浓度的增大，ｉ°的大小呈正态分布，其中Ｃｕ－３０镀液试片的ｉ°最大。与常规所用的Ｃｕ、Ｃｕ／Ｈｇ、Ｎｉ、蒙乃尔合金电极相比，Ｃｕ－３０试片的性能最佳，这与表观活化能所测结果相一致。
The performances of Cu- Ni alloy cathode in electrosynthsis of para-aminophenol arestudied by means of steady-state-polarization. It is indicated that the alloy cathodes with different Cu/Ni ratio have different exchange current density in the system for electrosynthsis ofPAP;the exchange current density is increased with increase of the concentration of Cu(Ⅱ) inthe electrodeposition solution. The size of i°submits to normal distribution. The alloy has themaxmum i° which is electrodeposited from the electrolyte contained 30% Cu(Ⅱ), and it hasmore suitable characterisics than other cathodes, such as Cu、Cu/Hg、Ni and Mondel alloy.
