Etude de la fixation du magnésium d'un milieu phosphorique sur résines échangeuses d'ions

Written by sctunisie no comments

The fixation of magnesium in phosphoric acid medium is studied on different types of cation exchange resins. On account of its high exchange capacity, the sulfonic resin Duolite C 20 is kept to check the factors (pH and metal concentration) governing the exchange phenomenon. After determination of the exchange constant the square diagram representative of the equilibria between phases is traced.
