摘要/Abstract

摘要： 针对氢氧化铬渣进行了无害化处理研究，考察了NaOH质量浓度、液固质量比、浸出温度、搅拌速率、浸出时间等条件对铬渣中Al的脱除率的影响.实验结果显示，在温度为100℃、NaOH质量浓度为150g/L、液固质量比为7∶1、搅拌速率为400r/min、浸出时间为3.5h的条件下，铬渣中Al的浸出率可以达到92.69%.碱浸渣水洗脱碱后，在950 ℃条件下煅烧90min，最终得到的产品中氧化铬的含量可达到97.23%，经过CIE L*a*b*表色体系测定，由铬渣制取的氧化铬产品偏绿，适用于工业用途.

关键词: 氢氧化铬渣, 无害化处理, 浸出渣, 铝的浸出率, 氧化铬的含量

Abstract: The harmless treatment of chromium hydroxide residue was studied. The effects of NaOH concentration， liquid to solid mass ratio， leaching temperature， stirring rate and holding time on the leaching rate of aluminum were investigated. The results show that the removal rate of aluminum from chromium residue can reach 92.69% when the temperature was 100℃， the NaOH concentration was 150g/L， the liquid to solid ratio was 7∶1， the stirring rate was 400 r/min and the holding time was 3.5h. After washing with water， the leaching residue was calcined at 950℃ for 90 min to produce chromium hemitrioxide， and its content reached 97.23%. The chromium hemitrioxide is green and suitable for industrial use according to the measurement with CIE L*a*b*colour space.

Key words: chromium hydroxide residue, harmless treatment, leaching residue, leaching rate of aluminum, chromium oxide content
