However, current sulfite treatment methods primarily focus on oxidation to inert sulfate or biological reduction, both of which suffer from low efficiency, secondary emissions, or loss of sulfur value. In this study, we present a sustainable electrocatalytic strategy for upgrading sulfite\u2010laden wastewater by directly converting SO\n                    <jats:sub>3<\/jats:sub>\n                    <jats:sup>2\u2212<\/jats:sup>\n                    into value\u2010added sulfonates under ambient conditions. Using commercial Ni catalysts and methanol as a representative feedstock, the system achieves a sulfite\u2010to\u2010sulfonate conversion ratio exceeding 90% after 3\u00a0h of continuous electrolysis, with a maximum sulfonate production rate of 7870\u00a0\u00b5mol\u00a0cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    \u00a0h\n                    <jats:sup>\u22121<\/jats:sup>\n                    at 1000\u00a0mA\u00a0cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    , highlighting efficient upgrading of sulfite\u2010laden wastewater into organosulfur products. To enable continuous system operation, Ni nanoparticles were incorporated into a carbon nanotube (CNT)\u2010based electrochemical membrane, which shows a sulfite removal ratio above 93% and a sulfite\u2010to\u2010sulfonate conversion ratio above 90%, demonstrating suitability for scalable wastewater treatment and sulfur valorization. Moreover, techno\u2010economic analysis reveals a minimum levelized production cost of $300.84 per ton at 400\u00a0mA, corresponding to an 79.85% reduction compared with conventional routes. This integrated electrocatalytic membrane system offers a promising route for coupling sulfite removal with organosulfur synthesis.\n
