中文摘要: 研究膨润土对高浓度氰化贫液中各离子的吸附作用,考察了温度、pH、吸附时间、膨润土用量等对吸附效果的影响。结果表明,膨润土吸附氰化贫液的最适宜的工艺条件为:膨润土投加量10 g/L、时间40 min、溶液温度25 ℃、氰化贫液pH=10(即氰化贫液的初始pH)。氰、铜和锌3种离子的吸附率分别达到56%、55%和93%。
Abstract:Adsorption of high content ions in cyanide barren solution with bentonite was studied. The effects of temperature, pH value, time, and bentonite dosage on adsorption were investigated. The results indicate that adsorption rate of CN-, copper, and zinc is 56%, 55%, and 93% respectively under the optimum conditions including dosage of bentonite of 10g/L, time of 40 min, temperature of 25 ℃, and pH value of cyanide barren solution of 10.
