Characterization of Acid-Aged Biochar and its Ammonium Adsorption in an Aqueous Solution.

ABSTRACT: According to its characteristics, biochar originating originating from biomass is accepted as a multifunctional carbon material that supports a wide range of applications. With the successfully used in reducing nitrate and adsorbing ammonium, the mechanism of biochar for nitrogen fixation in long-term brought increasing attention. However, there is a lack of analysis of the NH₄⁺-N adsorption capacity of biochar after aging treatments. In this study, four kinds of acid and oxidation treatments were used to simulate biochar aging conditions to determine the adsorption of NH₄⁺-N by biochar under acidic aging conditions. According to the results, acid-aged biochar demonstrated an enhanced maximum NH₄⁺-N adsorption capacity of pe
