Abstract

This dataset article presents the effective adsorption of Malachite Green (MG) dyes onto FZMC as low-cost agro-waste. The physicochemical parameters data of the FZMC (1329 m2/g surface area; 12% moisture content; 0.9% loss of mass on ignition; 0.386 g/cm3 bulk density) showed its suitability for sorption. Favorable adsorption of MG dye in a batch technique was achieved at pH 8, 120 min contact time through 100 – 600 ppm concentrations. With R2>0.98, the Pseudo second-order model best represented kinetic data. The mechanism was better represented by the intraparticle diffusion model. Equilibrium data were best described by Freundlich and confirmed by Halsey isotherm with R2>0.97 and physisorption nature of the d-R isotherm model (E (J/mol) <8 kJ/mol). Qmax of FZMC (64.52 mg/g) surpassed those previously reported. Surface chemistry and morphology were determined by FTIR and SEM. The dataset revealed FZMC as a promising biosorbent for the treatment of industrial wastewater.
