| 摘要 |
The invention relates to chemical coordinative structure compounds, namely to triple salt of copper (II), zinc and cadmium with ammonia and orthophosphate ion in solid state of general formula CuZnCd(PO)·2.5NH·3.0HO. The subject of the invention is that amorphous triple salt orthophosphate aquaaminocopper (II)-zinc-cadmium of a particular composition of general formula CuZnCd(PO)·2.5NH·3.0HO is prepared by solving of mechanical mixture of crystal Cu(PO)·3HO, Zn(PO)·4HO and Cd(PO)·5HO, taken in mole ratio Cu:Zn:Cd, equal to 0.75:0.75:1.5, in concentrated ammonia water solution with further compound deposition by phosphate ammonia solution infusion to the acetone, separation of bottom phase and its holding in air at 15÷25 °С to complete hardening and constant mass. |
