A simple gas chromatographic-mass spectrometric (GC–MS) method for the identification of components present in alkylsalicylaldoximes based metal extractants LIX860, LIX622, LIX622N, Acorga PT5050 and Acorga P5100 is described. These reagents have been developed for removing copper in hydrometallurgical processes. The extractants were analyzed by GC–MS in the Full Scan mode without any derivatization...
The extraction of Zn(II) from 1.0 M KCl by Cyanex 302 dissolved in toluene was studied as a function of the total extractant concentration, the equilibrium pH and the total metal concentration. Experimental data, treated both graphically, using curve-fitting analysis, and numerically, by the computer program letagrop-distr, can be explained by assuming the extraction of the species ZnClR(HR), ZnR...
