Abstract
Inventia se refera la un procedeu d eseparare a fierului din solutii apoase acide, de electroliti, prin extractie cu solutie de esteri ai acidului citric cu formula generala (I) în care cel putin unul si cel mult doi din radicalii R1, R2, R3 reprezinta un radical alchilic cu lant drept sau ramificat, cu 4...20 atomi de carbon si, de preferinta, un radical alchilic cu 6...13 atomi de carbon alesi dintre i-decil, i-dodecil, i-tridecil si respectiv, de preferinta, Z-etilhexil, si ceilalti din radicalii mentionati reprezinta hidrogen sau una tom de metal solubil în acizi alesi între Cu, Cd si respectiv, de preferinta, Zn solutie de esteri care are concentratia de 0,01...1,5 moli/l si, de referinta, 0,4...0,6 moli/l în solventi organici alesi, de preferinta, între kerosen si tricloretilena.
