Cation exchange studies of titanium(4+), vanadium(5+), iron(3+), niobium(5+), and uranyl(2+), ions in formic, oxalic, tartaric, and citric acid media

Cation and anion exchange studies of twenty cations in aqueous solutions of formic, oxalic, tartaric, and citric acids, and their alkali metal salts

“…In our earlier paper (1), we had shown that carboxylic acid media are useful for ion exchange separation of cations, and successful binary separations of Ti4+-U022+, Ti4+-V5+, Nb5+-V5+, and Ti4+-Fe3+ on cation exchange columns were achieved. Other papers have also described ion exchange separations of cations (2)(3)(4)(5).…”

“…The total volume of the equilibrating solution was 25 ml and the amount of resin taken was 0.50 gram. Other details are as described in our earlier paper (1).…”
