چکیده انگلیسی
The usage of anisomeric square pulse with fluctuating frequency for electrochemical generation of FeO42â has been reported. The cylinder electrolytic bath was constituted by a double cathode and a porous cast iron cylinder anode, using CS-CMC bipolar membrane as septum. Compared with CS or CMC membranes, CS-CMC BM has good mechanical strength and chemical stability in acid and alkali solution. FT-IR spectrum indicated that CS-CMC BM contained NCRH2+ and COOâ functional groups. The charge density of NCRH2+ in CS layer and COOâ in CMC layer was about 14.13 and 9.01Â mmol/g, respectively. With the aid of anisomeric square pulse, the oxidation layer was destroyed in time. After 6Â h electrolysis, the corresponding current efficiency was 51.2%.
