The adsorption of silver on potassium cyanocobalt(II)ferrate(II).

Abstract A procedure is described for recovering silver from industrial sewage (mining and photo-industry etc ) with the aid of the ion-exchanger potassium cyanocobalt(II)ferrate(II) (KCFC). Silver is easily removed by simple mixing with KCFC, even from solutions containing less than 1 g of silver per ton of solution. The process is performed at room temperature at pH
