Outline
Hydrothermal carbon generated by hydrothermal carbonization of waste jujube branches was activated with zinc chloride as an activator, and a kind of modified biochar was prepared with highly porous and aromatic structure on its surface, which was then used to adsorb Zn2+ in aqueous solution. It is shown that for the solution with pH of 9 and initial Zn2+ concentration of 30 mg/L, after 80 min adsorption at a temperature of 55 ℃ by adding 700 mg/L modified biochar, the removal rate of Zn2+ therein exceeds 99%. The adsorption process is well-fitted to the Freundlich adsorption model, indicating that the adsorption process with the modified biochar is a multilayer molecular adsorption. The removal rate of Zn2+ by the modified biochar, after 5 cycles of adsorption and desorption, can still remain over 97%.
