Title (EN) IMPROVEMENTS RELATING TO EXTRACTANTS
(FR) AMELIORATION RELATIVE A UN PROCEDE D"EXTRACTION
Abstract: front page image
(EN)An extraction process for extracting ionic values from an aqueous solution containing same , which comprises contacting the aqueous solution with an organic hydrophobic liquid extractant phase comprising an extractant for ions, the molecules of which extractant contain at least one hydrophobic group selected from cyclic phosphazene radicals, linear siloxane radicals, cyclic siloxane radicals, and three-dimensional siloxane radicals, and stripping resulting loaded extractant phase with an aqueous stripping liquid phase.
(FR)Un procede d"extraction de substances ioniques d"une solution aqueuse qui comprend la mise en contact de la solution aqueuse avec une phase liquide hydrophobe d"extraction contenant un agent d"extraction des ions, les molecules de cet agent comprenant au moins un groupe hydrophobe choisi parmi les radicaux phosphazene cycliques, les radicaux silicone lineaires, les radicaux silicone cycliques et les radicaux silicone tridimensionnels et l"epuisement de la phase d"extraction chargee avec une phase aqueuse liquide d"epuisement.
