Abstract
The invention discloses a separation method of zinc cyanide complex ions. The method is based on the principles that the coordination bond formed by Zn<2+> and the functional group -N<+>(CH2COO)2<-> of an Na<+> type D751 macroporous chelated styrene based ion-exchange resin is stronger than Zn(CN)4<2->, the coordination bonds of other heavy metal ions such as Fe<3+>, Cu<2+> and -N<+>(CH2COO)2<-> are weaker than metal cyanide complex ions such as Fe(CN)6<3-> and Cu(CN)4<2->, and the chelated resin does not adsorb the anions CN<->; according to the method, the cyanide-containing wastewater containing the metal cyanide complex ions are fed into the Na<+> type macroporous chelated resin for dynamic exchange adsorption, Zn<2+> enters the resin from the solution while Na<+> enters the solution from the resin, the exchange saturated resin is regenerated by use of an HCL solution in the mass percentage of 4%, and the regenerated solution is a ZnCl2 solution. The separation method is capable of realizing the separation of Zn(CN)4<2-> from other metal cyanide complex ions such as Fe(CN)6<3-> and Cu(CN)4<2-> in the solution, and the separation of Zn<2+> from CN<-> in Zn(CN)4<2->.
