| 摘要 |
The invention relates to new chemical compounds of coordination structure, namely to nickel(II)-zinc-cadmium triple salt with ammonia and orthophosphate ion in solid amorphous state of general formula NiZnCd.(PO)·n(NH) m(H0), where х + у2.25; х, у = 0.75-1.5; n = 2.9-3.5; m = 2.7-3.5. The process for the preparation of nickel(II)-zinc-cadmium triple salt, in which the fixed ratio between metals is provided by solving of mechanical mixture of crystal Ni(PO)·8HO, Zn(PO)·4HO and Cd(PO)·5HO, taken in fixed molar ratio NiO:ZnO:CdO, in excess of concentrated aqueous ammonia solution with a further sedimentation of solid compound by infusion of ammonia solution of phosphate into acetone and its air holding at 15-25 °С to full solidification and constant mass. |
