摘要:
工业生产所得的铜镍混合废液中含有大量的铜资源,具有合成碱式氯化铜的潜在价值,但同时存在处理工艺复杂、生产成本高及原料成本波动等问题,针对上述问题,开展了铜镍混合废液回收制备碱式氯化铜的研究。首先向铜镍混合废液中加入H2O2进行氧化,补加FeCl3调节体系中n(Fe)∶n(As)的值实现脱砷除铁等预处理工艺,再通过改变反应体系的pH、反应时间和反应温度制备碱式氯化铜。研究结果表明:预处理的最佳条件为H2O2加入量5 mL/L,氧化时间5 min,加入FeCl3调节体系n(Fe)∶n(As)=27,反应时间50 min,体系pH值4.0时,铁去除率达到98.9%,砷去除率达到99.9%; 制备碱式氯化铜的最佳条件为逐滴加入2 mol/L的氢氧化钠溶液调节pH为5.0,反应温度80 ℃,反应时间40 min,所得碱式氯化铜的产率达到97.1%,制备工艺未引入其他杂质离子,流程简便。
Abstract:
Copper-nickel mixed waste liquor generated in the industrial processes abounds in copper resources and has the potential for synthesizing basic copper chloride. To address the problems of intricate treatment procedures, high production costs and fluctuating raw material prices, we conducted research on recycling of the copper-nickel mixed waste liquor and preparing basic copper chloride from it. First, after adding H2O2 to the waste liquor for oxidation, we pretreated it by adding FeCl3 to adjust the ratio of n(Fe):n(As) in the system for arsenic and iron removal. Then, we prepared basic copper chloride by changing the pH,reaction time and temperature of the reaction system. The results showed that when the H2O2 addition amount is 5 mL/L,the oxidation time is 5 min, the ratio of n(Fe)∶n(As) is 27, the reaction time is 50 min and the pH is 4.0, the iron and arsenic removal rates can reach 98.9% and 99.9% respectively, which are the optimal pretreatment conditions; When 2 mol/L sodium hydroxide solution is added dropwise to adjust the pH to 5.0,the reaction temperature is 80 ℃ and the reaction time is 40 min, the yield of basic copper chloride can reach 97.1%, which are the best preparation conditions. The preparation process is simple and without any other impurity ions.
