摘要
以溶析法分离出硫酸锌和硫酸镁混合电解质饱和溶液中的硫酸镁。考察了溶剂种类、有机溶剂加入量、析出温度、静置时间等因素对分离效果的影响。结果表明,在最佳的分离条件下,混合电解质中硫酸镁的含量为90.8%,硫酸镁的析出率为94.2%。
The experiment of separating MgSO4 from their saturated aqueous solutions,concluding the compositions of MgSO4 and ZnSO4,was studied by using the method of solventing out.Different effects on the preparation were studied,such as the volume of organic solven,sorts of organic solvent,precipitation temperature,and resting time.The experiment results showed that the content of MgSO4 in the mixing precipition was 90.8% and the precipitation ratio of MgSO4 was 94.2% in the optimum separation conditions
