| description | The invention relates to a method for photocatalytic dissolution of metal by using a phosphate radical modified photocatalyst. The method comprises the following steps that a metal-containing material to be dissolved is dispersed into a mixed solution containing a nitrile compound and an organic chloride, an inorganic phosphate radical modified photocatalyst is added, oxygen is introduced or a substance capable of generating oxygen is added, metal is dissolved under the condition of light irradiation, and after the metal is dissolved, a metal organic coordination compound is formed in the solution and has the general formula of (NH4) xMCly. Compared with the prior art, the preparation process of the photocatalyst is simple and convenient, after inorganic phosphate modification, oxygen adsorption can be improved, more superoxide free radicals are generated, visible light absorption of the catalyst can be improved so as to enhance the reaction rate of photocatalytic dissolution of metal, a feasible scheme is pr |
