A biochar supported calcined-Mg/Al layered double hydroxides composite (CLDHs/BC) was synthesized by a one-pot slow pyrolysis of LDHs preloaded bagasse biomass. Multiple characterizations the product illustrated that (CLDHs) were successfully coated onto in pre-treated The as-synthesized CLDHs/BC could efficiently remove antibiotic tetracycline from aqueous solutions. coating CLDHs significantly increased adsorption ability biochar, and exhibited more than 2 times higher capacity pristine (BC) tested pH range. maximum for 1118.12 mg/g at 318 K. experimental results suggested interaction with on played dominant role adsorption, accompanied π–π hydrogen bond. This study provides feasible simple approach preparation high-performance material antibiotics contaminated wastewater treatment cost-effective way.
