Gold plated with a non-toxic salts and synthesis

The present invention discloses a non-toxic salts and synthesis plated with gold, the method comprising: Step S1: In the water under stirring gold trichloride was added to a 10 ~ 100 ℃; Step S2: to the three adding an aqueous solution of alkali metal chloride solution; step S3: to the mixed solution were added at a concentration of 0.1mol / L ~ 10mol / L and the concentration of reducing agent solution of 1.0mol / L ~ 10mol / L complexing solution, to give a clear transparent solution; step S4: in the step S3, the clear and transparent solution was placed in a cooling vessel was cooled to -20 ~ 10 ℃, the solution was cooled again adding a strong base solution, such a solution appears precipitation of crystals, the solution is kept continued at this temperature for 6 to 48 hours of cooling, so that precipitation of crystals sufficiently precipitate, and drying, to obtain a non-toxic salt thereof plated with gold. The present invention is non-toxic and environmentally friendly, stable, strong adhesion ability to a different base coating, which can effectively protect the external environment corrosion of the matrix.
