Glyphosate Removal from Water Using Biochar Based Coffee Husk Loaded Fe3O4

Glyphosate is an herbicide that usually used by farmers and considered harmful to the environment in excess amounts. To address these issues, coffee-husk-biochar-loaded Fe3O4 (CHB- Fe3O4) was as adsorbent remove glyphosate from water. CHB-Fe3O4 characteristics such pHpzc, FTIR, SEM were measured understand properties of this adsorbent. The best conditions for removal obtained at pH 2.0, where adsorption capacity percentage are 22.44 mg/g 99.64%, respectively, after 4 h adsorption. Freundlich model provided fit isotherm, demonstrating multilayer sorption. most effective characterizing kinetics pseudo-second-order with a chemical mechanism. desorption studies found use 0.1 M NaOH concentration effectively desorb 69.4%. This indicates CHB- feasible
