AB An innovative approach to the treatmentof textile wastewater by utilizing fine fractions ofconstruction and demolition waste (CDW) as a costeffectiveadsorbent is presented in this work. Throughbatch experiments, the impact of key parameters onthe adsorption process was explored, identifying optimalconditions: natural pH, adsorbent dosage (S/L) of20 g L−1, and temperature of 20 °C. The characterizationof CDW was performed using ICP, BET, FTIR,SEM–EDX, XPS, and XRD. The kinetics of adsorptionwere effectively described by the Elovich model,while equilibrium adsorption data showed goodagreement with the Freundlich model. The maximummonolayer adsorption capacity for acid blue AB113dye on CDW obtained from Langmuir isotherm was89.52 mg g–1. Thermodynamic analysis indicated anexothermic and feasible nature of the adsorption process.The results of this study highlight the potentialuse of fine CDW as a promising adsorbent to removeacid blue113 dye from textile wastewater
