Efficient recovery of gallium (Ga) from vanadium slag processing residue (VSPR) solution is great significance for environmental protection and resource utilization, but improving its selective adsorption against the coexisting Sc3+ In3+ still challenging. Herein, a novel adsorbent consisting 4-amino-3-hydrazino-1,2,4-triazol-5-thiol (AHTZT)-modified graphene oxide (GO-AHTZT) was successfully synthesized that exhibits higher selectivity Ga3+ in VSPR with In3+. Under optimal conditions, capacity GO-AHTZT can reach 23.92 mg g−1, which 4.9 12.6 times than (4.87 g−1) (1.90 adsorption, indicating excellent anti-interference ability The process mechanism onto also studied discussed detail. By measuring by characterizing before after we demonstrate interaction between Ga3+- N-containing groups AHTZT main reason improved selectivity. This work opens up an avenue design synthesis highly adsorbents complex solutions.
