The design and development of new precious metal recovery adsorbents have significant socio-economic benefits; this study successfully synthesized a high-performance gold ion adsorbent, UiO-66-TMB, by modifying UiO-66-NH₂ with thiosemicarbazide, a common industrial chemical rich in amino and thiol groups. The obtained material exhibits excellent stability and adsorption performance, with the maximum adsorption capacity of 729.15 mg·g −1 at pH = 2. The adsorbent has good recyclability and can maintain superior selectivity in environments cont...
