| Abstract: | The way of separation of gold from silver by ion-exchanging resin ia the system of H2SO4-CSINH2)2-H2O is another successful one. The shanghai 744 resin of phe-nethylene type posseses very good adsorption for Au(SCN2H4)2]+ and Ag(SCN2H4)s]+.Since its big porous structure character, it is more suitable for adsorbing bulker complexions. HCL-Br2(-aqu) solution is given as elution reagent for gold and HCL solution is for silver. Through experiment with single factor and orthogonal experiments varied factors,the optimum conditions for adsorption and deadsoption are given. |
