| Abstract: | The exchange characteristics of PP based anion exchange fiber for palladium in a hydrochloric acid solution are investigated, and the effects of pH value, solution temperature, the concentration of Cl - in the solution, and exchange time on the adsorption and recovery are discussed. The most suitable adsorption conditions are determined and the maximal static exchange capacity determined. The exchanged palladium can be quantitatively desorbed with the mix solution of 2% thiourea and 2 mol/L hydrochloric acid. Trace palladium in the solution can be quantitatively recovered by this PP based anion exchange fiber. |
