Extraction of Lanthanum (III) Ion from Aqueous Solutions using Formazan Reagent by Liquid-liquid Method


Abstract in English

The current study included a liquid-liquid extraction of the trivalent lanthanum ion by means of the reagent ((3,1-diphenyl-5-(p-nitrophenyl)formazane)), and the effect of various factors was studied on the percentage of extraction and the extraction coefficient, including the pH of the medium. , Mixing the two phases, the concentration of the studied ion, and also the effect of the presence of some competitive positive ions, and the effect of the extraction process in batches, in addition to studying the effect of the ratio of the organic phase to the aqueous phase.
