In this study, use of low-cost nutraceutical industrial coriander seed spent (NICSS) for removing Acid Blue 113 (AB113) from aqueous solution has been explored. Biosorption studies were done under varying conditions of initial pH, initial dye concentration, adsorbent dosage, particle size of the adsorbent and temperature to assess the adsorption capacity, kinetics and equilibrium thermodynamics. Optimal adsorption took place at acidic pH. A two-level fractional factorial experimental design (FFED) and analysis of variance (ANOVA) showed that a maximum adsorption value of 90.00 mg/mL was possible. The influence of each parameter and combination of parameters on the final adsorption capacity of the system was studied. The dye uptake followed a pseudo-second order kinetic paradigm and was best described by the Langmuir isotherm. Intra-particle diffusion showed that the adsorption mechanism was more governed by external mass transfer. AB113 adsorption on NICSS was endothermic and almost spontaneous. The NICSS has a highly fibrous matrix with hierarchical porous structure as evidenced by SEM images. Analysis of the spent showed that it possesses cellulosic and ligno-cellulosic materials having both hydrophilic and hydrophobic properties. The results proved that NICSS efficiently removes AB113 from water and textile industrial effluents. © 2019 Desalination Publications. All rights reserved.
