[0023] The present invention will be further described below in conjunction with specific embodiments, but the protection scope of the present invention is not limited to this:
[0024] This embodiment includes the following steps:
[0025] 1. Add 30mL of deionized water, 6.0g of iron powder, 6.0g of ferroferric oxide, 6.3g of hexachloroethane and 144g of stainless steel balls to the grinding tank of the grinder, and ball mill for 180min at 600 rpm to obtain A mixed slurry containing degradation products of amorphous carbon, ferrous chloride and ferric chloride (also contains unreacted iron powder and ferroferric oxide).
[0026] 2. Suction filtration of the degradation product obtained in step 1 to remove the formed amorphous carbon solid, unreacted iron powder and ferroferric oxide to obtain a mixed solution containing ferrous chloride and ferric chloride; the mixed solution is green, The volume of the filtrate was 30 mL.
[0027] 3. Add 1 mL of hydrogen peroxide with a mass fracti...
