The leaching of arsenic with air oxidation method in an alkaline system was studied. Based on the results of thermodynamic analysis, the influence of different factors on the leaching process was investigated. The leaching residue was characterized by XRD and SEM, and the leaching kinetics was discussed. The results show that under the optimized conditions of initial NaOH concentration of 2 mol/L, leaching temperature of 60 ℃, liquid volume to solid mass ratio of 10 mL/1 g, and leaching time of 168 h, the arsenic leaching rate reaches 91.9%. The leaching rate of As is jointly controlled by diffusion and chemical reactions, with apparent activation energy of 83.41 kJ/mol. The method can achieve the purpose of arsenic removal under normal pressure in an alkaline system and has certain value for promotion and application.

研究了在碱性体系中用空气氧化法浸出砷。基于热力学分析结果,考察了不同因素对浸出过程的影响,采用XRD和SEM对浸出渣进行了表征,并探讨了浸出动力学。结果表明,在NaOH初始浓度2 mol/L、浸出温度60 ℃、液固体积质量比10 mL/1 g、浸出时间 168 h的优化条件下,砷浸出率达91.9%;砷浸出速率受扩散和化学反应混合控制,表观活化能为83.41 kJ/mol。该法可在常压、碱性体系中实现脱砷,具有一定推广应用价值。

研究了在碱性体系中用空气氧化法浸出砷。基于热力学分析结果,考察了不同因素对浸出过程的影响,采用XRD和SEM对浸出渣进行了表征,并探讨了浸出动力学。结果表明,在NaOH初始浓度2 mol/L、浸出温度60 ℃、液固体积质量比10 mL/1 g、浸出时间 168 h的优化条件下,砷浸出率达91.9%;砷浸出速率受扩散和化学反应混合控制,表观活化能为83.41 kJ/mol。该法可在常压、碱性体系中实现脱砷,具有一定推广应用价值。

The leaching of arsenic with air oxidation method in an alkaline system was studied. Based on the results of thermodynamic analysis, the influence of different factors on the leaching process was investigated. The leaching residue was characterized by XRD and SEM, and the leaching kinetics was discussed. The results show that under the optimized conditions of initial NaOH concentration of 2 mol/L, leaching temperature of 60 ℃, liquid volume to solid mass ratio of 10 mL/1 g, and leaching time of 168 h, the arsenic leaching rate reaches 91.9%. The leaching rate of As is jointly controlled by diffusion and chemical reactions, with apparent activation energy of 83.41 kJ/mol. The method can achieve the purpose of arsenic removal under normal pressure in an alkaline system and has certain value for promotion and application.
