摘要通过热力学理论计算预测Me-OH-, Me-OH--NH3体系溶液中金属离子浓度与pH值的关系，分析了不同配合-沉淀体系中铝与钴、镍、锰的分离性能，采用水解-沉淀法除铝. 结果表明，在Me-OH--NH3和Me-OH--NH3-CO32-体系中，铝与镍、钴、锰分离效果较好，在Me-OH--NH3-CO32-体系中生成的Al(OH)3过滤性能较好. 在Me-OH-- NH3-CO32-体系中，pH=4.5时，镍、钴、锰回收率分别为98.57%, 99.63%和99.91%，铝去除率为99.94%.

Abstract：The separation of aluminum from nickel, cobalt and manganese in complexation-precipitation systems was studied. The relationships between metal ion concentration and pH value in the systems of Me-OH- and Me-OH--NH3 were simulated by thermodynamic calculation. Aluminum was eliminated of by hydrolysis-precipitation method. The results showed that separation of aluminum from nickel, cobalt and manganese in sulfate solution was effective in the Me-OH--NH3 and Me-OH--NH3-CO32- systems. When the pH value was 4.5, the recovery rate of nickel, cobalt and manganese was 98.57%, 99.63% and 99.91%, respectively, and the removal rate of aluminum 99.94%.
