[0020] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.
[0021] A potassium chloroplatinite (K 2 PtCl 4 ) and potassium chloroplatinate (K 2 PtCl 6 ) joint preparation method whose steps are:
[0022] ⑴Preparation of chloroplatinic acid solution: Put 100 grams of metallic platinum (sponge platinum, platinum sheet, and platinum wire) into a glass beaker, add 600 ml of hydrochloric acid and 200 ml of nitric acid, heat to dissolve the metallic platinum, and dissolve the solution after all the platinum is dissolved. Concentrate to about 300 ml, add 400 ml of hydrochloric acid and continue to heat and concentrate to drive off the remaining nitric acid and nitrogen compounds. This process needs to be repeated three times, and finally the solution is concentrated to about 100 ml to obtain a chloroplat...
