Metal ion separations using cellulose phosphate as an ion-exchanger.
Cellulose phosphate is used as a chelating ion-exchanger to effect the separation of several metal ions. Its exchange rate is much more rapid than that of a chelating ion-exchanger containing phosphonic acid groups on a polystyrene matrix. Weight distribution coefficients as a function of hydrogen ion concentration on cellulose phosphate are given for several metal ions. Successful separations of rare earths and alkaline earths, alkaline earths and alkali metals and aluminium and alkaline earths have been achieved on cellulose phosphate columns.
