Preparation and Characterization of Apricot Kernel Shell Biochar and Its Adsorption Mechanism for Atrazine

In this study, the preparation of apricot kernel shell biochar by a hydrothermal method and its adsorption mechanism for atrazine was studied scanning electron microscopy (SEM) infrared spectrum (FTIR) analytical techniques. The results show that prepared from has an evenly distributed, nonaggregated carbon microsphere structure contains large number oxygen-containing groups. higher temperature is, more functional groups exist better potential performance is. kinetics on were fitted with quasi-second-order kinetic equation (R2 ≥ 0.995, p < 0.05). isothermal data in accordance Freundlich model 0.911, includes two processes: surface diffusion. capacity increases increasing decreases pH Ca2+ concentration. hydrogen bonding hydrophobic interactions. Therefore, shells, agricultural waste, exhibits good application prospect addressing non-point source pollution, especially pesticide residue pollution control.
