Recyclability of (a) DTC-g-PE-DA@GB@PU toward 10.0 μg mL⁻¹ Cu²⁺, Pb²⁺ and Cd²⁺. Other conditions: solution pH = 6; volume, 20 mL; adsorbent dose, 20 mg; temperature, 25 °C; (b) recyclability of PE-DA@GB@PU toward 1.0 μg mL⁻¹ Pd²⁺, Pt⁴⁺, and Au³⁺. Other conditions: solution pH = 0; volume, 20 mL; adsorbent dose, 20 mg; temperature, 25 °C.
