Characterization of biochars from woody agricultural wastes and sorption behavior comparison of cadmium and atrazine

Abstract Woody agricultural wastes have created enormous pressure on the environment. In this study, mulberry and cinnamon woodchips were reclaimed prepared for biochars through pyrolysis technique at four different temperatures. Physicochemical properties showed that biochar exhibited higher pH, CEC ash content than each temperature. All utilized as adsorbents to remove cadmium (Cd) atrazine (AT) from water. The adsorption isotherms found be well fitted by Freundlich Langmuir models. maximum capacities 5306.41 mg/kg Cd 538.89 AT adsorption, respectively. Moreover, principal component analysis, XPS FTIR analysis proved precipitation with phosphate in acted key property governed capacity of Cd, whereas porosity demonstrated a significant impact AT. Partial least squares (PLS) model was considered more favorable predicting adsorption. results present paper will helpful selecting most effective locally available woody byproducts are optimized contaminants removal
