The aim of this study is to discover the potential use nutraceutical industrial cumin seed spent (NICUS) as an economical biosorbent for eliminating acid blue 113 (AB113), azo dye, from water. investigates influence pH, adsorbent dosage, temperature, particle size, and initial dye concentration on adsorption AB113. Various isotherm models kinetic were studied. At equilibrium situations, maximum trial volume (qe) was found be 96 mg g−1. main objective determine suitability pseudo-second-order model describing kinetics adsorption. Thermodynamic parameters ΔG0ΔH0ΔS0 revealed that process endothermic non-spontaneous. lower value ΔH0 suggests a physical process. Analysis using FTIR SEM spectra confirmed NICUS surface effectively adsorbed emerges promising efficient deduction AB113 aqueous solutions.
