Abstract

This study treated Acid black 210 dye contaminated textile wastewater by adsorption and photocatalytic techniques using zinc ferrite nanoparticles. Zinc ferrite nanoparticles were formed by the green synthesis technique using eucalyptus leaves as reducing and capping agents. SEM, EDAX, XRD, BET, Zeta potential, and FTIR techniques identified the resulting zinc ferrite nanoparticles. The images from the SEM indicated the crystallinity and spherical shape of the zinc ferrite nanoparticles with a particle size of 32 nm. In addition, this study involved using a photoreactor to accomplish the photo-degradation process. Effect of the main factors on the adsorption and photocatalytic degradation of dye was examined. Based on adsorption results, the removal efficacy of dye after 180 min was 74% at optimum conditions of 5 mg/L, 0.75 g/L, 5, and 45 °C for AB210 concentration, Zinc ferrite nanoparticles dosage, pH, and temperature, respectively. In contrast, the photodegradation results show that five mg/L of dye was entirely removed within 30 min at optimal pH of 7, UV-intensity 24 W/m2, and a temperature of 45 °C. The adsorption isotherms were studied using Freundlich, Langmuir, Temkin, and Dubinin models.
