Popis: A model was prepared for the preparation of biochar from the biomass of mushroom residue at different carbonization temperature (350 °C,450 °Cand 550 °C) for adsorption characteristics of ammonium nitrogen in water through different ammonium nitrogen concentration, reaction time, pH and temperature. The investigation result showed that the adsorptive amount of these three biochar substances increased quickly with the initial concentration (0-2 h) and the adsorption equilibrium was reached after 4 hours. The adsorptive amount of these three biochars increased with the rise of pH from 5 to 9. Different temperature preparation of biochar on ammonium nitrogen adsorption increases with the rise of temperature. Different temperature preparation of biochar on ammonium nitrogen adsorption amount is in the order of 550 °Cbiochar > 450 °Cbiochar > 350 °Cbiochar.
