Increase in the antibiotic's usage and mis-management antibiotics' disposal has led to occurrence of antibiotic residues surface water bodies. These may pose considerable risks human as well aquatic organisms owing enhancement antimicrobial resistance among microbes. Hence, precautionary measures are need hour curtail compounds water. In addition, rampant burning agricultural waste India causes air pollution. Considering this, a novel adsorbent been developed from biomass, viz. wheat straw (WS), through calcination (CWS), followed by chemical activation (AWS). adsorbents were employed for removal ciprofloxacin (CIP) Removal efficiency 90% (for CWS) 98% AWS) could be achieved at neutral pH room temperature conditions. The maximum adsorption capacity on synthesized was evaluated 14.51 mg g-1. Experimental findings further explored get insights isotherm, kinetics, thermodynamics involved process. It found that Langmuir model (with R2 value 0.985) provided better fit than other isotherm models. Kinetics thermodynamic studies revealed process pseudo second order linear kinetic 0.999) with endothermic spontaneous sorption adsorbent. Thus, suitably used antibiotics
