specific Embodiment approach 1
[0026] Specific embodiment one: this embodiment is a method for electrochemically reclaiming hexavalent chromium with a CuS modified carbon cloth electrode, specifically as follows:
[0027] 1. Soak the carbon cloth in concentrated nitric acid aqueous solution for 24h to 25h, then rinse it with deionized water until it becomes neutral, and then dry it at 80°C to 85°C for 2h to 2.5h to obtain acidic carbon cloth;
[0028] 2. Dissolve copper sulfate pentahydrate and thioacetamide together in deionized water and stir for 30-40 minutes to obtain a mixed solution, then put it into a polytetrafluoroethylene autoclave, and then put the acidic carbon cloth prepared in step 1 completely Immerse in the mixed solution, react at 180°C to 190°C for 12h to 13h, then take out the carbon cloth and wash it with deionized water, and then dry it at 80°C to 90°C for 3h to 4h to obtain a CuS modified carbon cloth electrode;
[0029] The mass ratio of described copper sulfate pentahydrate and thioa...
specific Embodiment approach 2
[0032] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the carbon cloth model described in step 1 is HCP331N. Others are the same as the first embodiment.
specific Embodiment approach 3
[0033] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the mass fraction of the concentrated nitric acid aqueous solution described in step one is 69%. Others are the same as those in Embodiment 1 or 2.
