摘 要: 研究了NH2OH·H2O、蔗糖、葡萄糖酸鈣等添加劑在電解法制備氧化亞銅過(guò)程中的作用機(jī)理及對(duì)氧化亞銅產(chǎn)品質(zhì)量的影響。結(jié)果表明，NH2OH·H2O、蔗糖能有效地抑制電解過(guò)程中CuO的生成，但不能防止陰極區(qū)海綿狀金屬銅粉的生成；而葡萄糖酸鈣不僅能有效地阻止陰極區(qū)海綿狀金屬銅粉的生成，并且可以降低產(chǎn)品中CuO含量。因此，NH2OH ·H2O、蔗糖只能作為一種輔助添加劑，而葡萄糖酸鈣的作用較上述兩種添加劑的效果好，可作為獨(dú)立的添加劑使用，是一種較理想的添加劑。

Abstract:The effects of additives such as NH2OH·H2O, sucrose, calcium gluconate on the qualities of cuprous oxide and the action mechanism in the process of electrolysis were studied. The results suggested that NH2OH·H2O and sucrose can inhibit the deposition of CuO, but can not inhibit the deposition of copper in the electrolysis process. Calcium gluconate can not only effectively prevent the deposition of spongy copper powder on the cathodes, but also reduce the CuO content in the Cu2O product. So NH2OH·H2O and sucrose can be used as auxiliary additives in the electrolysis process. Calcium gluconate is a kink of ideal additive in the process of electrolysis to produce cuprous oxide, and can be used as an independent additive in the electrolysis process.
