The behavior of a chelating resin RCSP, macroreticular styrene-divinylbenzene copolymer-based methylenephosphonic acid resins, in the adsorption and desorption of molybdenum(VI) was studied. The resin exhibits the maximum uptake of molybdenum(VI) as high as 3 mmol/g around pH 1, and no uptake in the pH region higher than 7. Thus, molybdenum(VI) adsorbed on RCSP from acidic solutions was quantitatively eluted with aqueous sodium hydroxide as well as with aqueous sodium acetate, indicating the promising use of the resin in the separation of molybdenum(VI) from other metal ions.
