Sulfosalicylic acid (SSA) was selected as the optimal coordination agent. Under the optimal extraction conditions, the single-stage extraction efficiency of vanadium reached 89.2%, which is 11.5% higher than that of the conventional D2EHPA system. After stripping with H2SO4, the vanadium concentration in the vanadium-rich solution reached 32.67 g\/L, while the Fe2+ concentration was only 0.61 g\/L. Mechanism studies indicate that vanadium mainly exists in the form of VO[C7H4O6S] complex. The V\u2013O coordination bond in VO[C7H4O6S] is relatively long and its binding energy is low, making it easy to dissociate and release VO2+. In contrast, Fe[C7H4O6S] formed between Fe2+ and SSA has the shortest coordination bond and the highest binding energy, allowing it to be stably fixed in the aqueous phase, thereby effectively reducing the interference of iron ions in the extraction process. At the extraction interface, VO[C7H4O6S] acts as a carrier to transport VO2+ while capturing H+ released by D2EHPA, thus promoting the forward extraction reaction. In summary, the SSA-D2EHPA system achieves efficient vanadium extraction through a \u201cselective coordination-interface dissociation\u201d mechanism.<\/jats:p>","DOI":"10.1021\/acsomega.6c07290","type":"journal-article","created":{"date-parts":[[2026,9,18]],"date-time":"2026-09-18T12:01:17Z","timestamp":1789732877000},"page":"57985-57997","source":"Crossref","is-referenced-by-count":0,"title":["Functional Study\nof Metal Complex Formation with Sulfosalicylic\nAcid on Targeted Extraction of Vanadium"],"prefix":"10.1021","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-0154-3587","authenticated-orcid":true,"given":"Yiping","family":"Wang","sequence":"first","affiliation":[{"name":"Wuhan University of Science and Technology , , , ,","place":["Wuhan, Hubei, China, 430081"]},{"name":"State Environmental Protection Key Laboratory of Mineral Metallurgical Resources Utilization and Pollution Control , , ,","place":["Wuhan, Hubei, China, 430081"]},{"name":"Collaborative Innovation Center of Strategic Vanadium Resources Utilization , , ,","place":["Wuhan, Hubei, China, 430081"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nannan","family":"Xue","sequence":"additional","affiliation":[{"name":"Wuhan University of Science and Technology , , , ,","place":["Wuhan, Hubei, China, 430081"]},{"name":"State Environmental Protection Key Laboratory of Mineral Metallurgical Resources Utilization and Pollution Control , , ,","place":["Wuhan, Hubei, China, 430081"]},{"name":"Collaborative Innovation Center of Strategic Vanadium Resources Utilization , , ,","place":["Wuhan, Hubei, China, 430081"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yimin","family":"Zhang","sequence":"additional","affiliation":[{"name":"Wuhan University of Science and Technology , , , ,","place":["Wuhan, Hubei, China, 430081"]},{"name":"State Environmental Protection Key Laboratory of Mineral Metallurgical Resources Utilization and Pollution Control , , ,","place":["Wuhan, Hubei, China, 430081"]},{"name":"Collaborative Innovation Center of Strategic Vanadium Resources Utilization , , ,","place":["Wuhan, Hubei, China, 430081"]},{"name":"Hubei Provincial Engineering Technology Research Center of High Efficient Cleaning Utilization for Shale Vanadium Resource , ,","place":["Wuhan, Hubei, China, 430081"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0356-953X","authenticated-orcid":true,"given":"Pengcheng","family":"Hu","sequence":"additional","affiliation":[{"name":"Wuhan University of Science and Technology , , , ,","place":["Wuhan, Hubei, China, 430081"]},{"name":"State Environmental Protection Key Laboratory of Mineral Metallurgical Resources Utilization and Pollution Control , , ,","place":["Wuhan, Hubei, China, 430081"]},{"name":"Collaborative Innovation Center of Strategic Vanadium Resources Utilization , , ,","place":["Wuhan, Hubei, China, 430081"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tao","family":"Liu","sequence":"additional","affiliation":[{"name":"Wuhan University of Science and Technology , , , ,","place":["Wuhan, Hubei, China, 430081"]},{"name":"State Environmental Protection Key Laboratory of Mineral Metallurgical Resources Utilization and Pollution Control , , ,","place":["Wuhan, Hubei, China, 430081"]},{"name":"Collaborative Innovation Center of Strategic Vanadium Resources Utilization , , ,","place":["Wuhan, Hubei, China, 430081"]},{"name":"Hubei Provincial Engineering Technology Research Center of High Efficient Cleaning Utilization for Shale Vanadium Resource , ,","place":["Wuhan, Hubei, China, 430081"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,18]]},"reference":[{"key":"2026092911123338000_cit1","doi-asserted-by":"publisher","first-page":"110923","DOI":"10.1016\/j.jece.2023.110923","article-title":"Simultaneous stripping and regeneration of chelate\nstructure of vanadium through vanadium reduction and conversion in\nvanadium-bearing shale extraction","volume":"11","author":"He","year":"2023","journal-title":"J.
