摘　　要：采用电化学法制取氧化亚铜 ,研究了电解液组成及其浓度、温度、电流密度以及添加剂等因素对氧化亚铜产品质量的影响 ,得到了电化学法制备氧化亚铜的优化工艺条件 :ρ( Na Cl) =2 60～ 2 90 g/ L,ρ( Na OH) =0 .5 g/ L( p H1 2 .1 ) ;电解温度 :75～ 80℃ ;电流密度 :75 0～ 1 0 0 0 A/ m2 ;ρ( Na2 Cr2 O7) =0 .1 g/ L。在此条件下 ,可以得到 Cu2 O纯度 >95Cuprous oxide powder is produced by electrochemical method.The effect of operating conditions such as the concentration and temperature of electrolyte,anode current density and additive on the quality of cuprous oxide is studied.The optimal conditions for preparing cuprous oxide by electrochemical process are determined:ρ(NaCl)=240g/L,ρ(NaOH)=0.5g/L(pH12.1),temperature:75~80℃,anode current density:750~1000A/m 2,ρ(NaCr 2O 7)=0.1g/L.Under these conditions the product with Cu 2O%>95% was obtained.
