| 中文摘要 | in this work, studies were carried out on the extraction properties of mn(ii) and mno4- in sulfuric acid medium using cyanex 923. effects of different variables on the extraction of mn(ii) and mno4-, such as the concentrations of acid, the extractant, and the temperature, were investigated. results indicated that mn(ii) was extracted weakly by cyanex 923; however, mno4- could be strongly extracted into the organic phase. the extraction mechanism of mno4- was proposed, and the influence of mno4- on the extraction of cerium was identified when kmno4 as oxidizer added into the bastnasite sulfuric acid leaching liquor. as mno4- was easier to be extracted into the organic phase than ce(iv) and then lost its ability for oxidization, a new device was designed to realize sufficient oxidization of cerium from iii to iv, and which has been applied to industrialization. |
