진한 염산용액에서 구리(II)와 알루미늄(III)이 Alamine336에 의한 백금(IV)과 팔라듐(II)의 추출 및 분리에 미치는 영향 (Effect of Cu(II) and Al(III) on the Extraction and Separation of Pt(IV) and Pd(II) from Concentrated Hydrochloric Acid Solution with Alamine336)

초록

The effects of Cu(II) and Al(III) on the extraction and separation of Pt(IV) and Pd(II) have been investigated in a mixed chloride solution using Alamine336 as the extractant. In the HCl concentration range of 1 to 5 M, more than 99% of Pt and Pd could be extracted by Alamine336 from all of the mixed chloride solutions investigated in this study. Lower HCl concentration led to a higher separation factor between Pd and Pt when Alamine336 concentration was constant. Extraction percentage of Cu increased with the increase of HCl concentration, while that of Al was nearly constant at 33% in our experimental range. The optimum conditions to extract Pt and Pd from Cu or Al and the separation factor under these conditions were obtained.
