내열합금 침출액으로부터 Alamine304-1을 이용한 금속이온의 용매추출 거동 및 레늄의 추출

Solvent extraction behaviors of metals from the leaching solution of super alloys which are increased to the industry of automobiles and the others were investigated to the recovery of metal ions. The effects on the concentration of extractants, pH of aqueous phase, concentration of HCl in aqueous phase and impurities were performed. Alamine304-1 as anion extractant, Cyanex272 and D2EHPA as cation extractants were used solvent extractants by distilled kerosene. After solvent extraction experiments from mixed solution of Al, Re, Co and V was resulted that Re was extracted to 99% but the other metals were not extracted. And the results of extraction percentage from mixed solution as Mo, W, Cr and Re were 99% of Re, 89.3% of Mo , 68.2% of W and 90.9% of Cr. The extraction percentage of Re at the range of 0-2 pH were about 99 but the percentage was shown 0% in the case of pH 4. by Alamine304-1 as cation extractant was higher than the other extractants as Cyanex272 and D2EHPA and the percentage is about 99%.
