초록
염산 용액에서 코발트(II)와 망간(II)의 이온평형을 해석하여 염산농도에 따른 착물의 농도분포를 구했다. 염산농도 4에서 10 M 사이의 범위에서 코발트의 대부분은 CoCl2로, 망간은 MnCl3-와 MnCl2로 존재한다. Alamine336에 의한 코발트와 망간 추출반응의 평형상수를 이용하여 두 금속의 등온추출곡선을 구했다. 망간 추출반응의 평형상수가 코발트의 평형상수보다 크나, 등온추출곡선을 비교하면 동일한 추출조건에서 코발트가 망간보다 Aalmine336에 효율적으로 추출된다
Abstract
Distribution diagram of CoCl2 and MnCl2 was obtained by analyzing ionic equilibria of the two metals in HCl solution. In the HCl concentration range of 4 and 10 M, most of cobalt exists as CoCl2, whereas Mn exists MnCl3- and MnCl2. Extraction isotherm of Co(II) and Mn(II) was calculated by using the equilibrium constant for the solvent extraction of the two metals by Alamine336. Although the equilibrium constant for the solvent extraction of Mn was higher than that of Co, extraction isotherm indicated that cobalt could be extracted more efficiently than manganese at the same initial extraction conditions
