Abstract

Abstract:

In order to find an effective method to control heavy metal nickel pollution and clarify the adsorption capacity and mechanism of tea residue-based biochar, the characterization and adsorption mechanism of tea residue-based biochar (TBC-700) were studied by scanning electron microscope (SEM), laser particle size analyzer and Zeta potential, and the adsorption process was determined by UV spectrophotometer. The results showed that synthesized TBC-700 had a relatively loose pore structure, and the adsorption process of nickel was more consistent with the pseudo-second-order kinetic model (R²>0.99) and Freundlich isotherm model (R²>0.95). The adsorption of nickel by TBC-700 was multi-molecular layer adsorption with 42.91% removal rate, and the maximum equilibrium adsorption capacity was 584.58 mg/g. The desorption rate of adsorbed nickel by TBC-700 could reach 62.33% in 500 mg/L KH₂PO₄ solution, showing a certain cyclic adsorption capacity.

Key words: biochar, tea residue, heavy metal nickel, adsorption, desorption
