| Abstract: | This thesis report that N 7207 extract Mo(VI) from mineral acid body system,and study the main factors that affect the extraction balance,and select the inverse extraction condition.The best condition of N 7207 extracting Mo(VI) is that the pH of beginning water is 2 3,and the density of the extractant is 0 01 mol/L.By Secondary extraction,the efficiency of extraction is 99 40%.The inverse efficiency of extraction is 100% by NaOH of 0 5 mol/L.By ultraviolet and visible spectrum,the mechanism that N 7207 extracts Mo(VI) is anion displacement reaction that attribute to ion association object extraction body system is discussed. |
