| Abstract: | The present paper deals in detail with the function of Na2SO3 in determination of gold-loaded carbon and purification of gold. With the character of high selectivity, less interference and needs less types of reagent, This method has been applied in practice with simple operation and higher accuracy. Gold in sample can be recover directly. This method also can be used for purification of gold-loaded carbon and alloy gold .Rate of purification is 99.30%-99.80%. It is applicable for smaller gold mine enterprise especially with satisfactory, results. |
