ABSTRACT
In this study, the effect of environmental parameters such as pH, temperature, initial dye concentration and adsorbent concentration on the adsorption of synthetically prepared Reactive Black 5 (RB 5) dye solution to antimicrobial ZnF (ZnFe2O4) nanoparticles in a batch system was investigated. The amount of RB 5 adsorbed per unit adsorbent mass was determined as 97.48 mg g-L at T=45oC and pH=2 value, the removal percentage was determined as 82.21% at these adsorption conditions. The kinetic, equilibrium and thermodynamic analysis of the system were carried out theoretically and experimentally, and the behavior of the adsorption system was interpreted with different equilibrium, thermodynamic and kinetic model equations. Temkin isotherm model has determined as the best repesentative model for RB 5-ZnFe2O4 adsorption system and the experimental kinetic data for the same adsorption system fits the second-order kinetic model. One of the reasons why antimicrobial Zn-based composite nanomaterial is preferred for the removal study is selectivity of nanoparticle. Another advantage of these nanoparticles is their fabrication suitability for multiple applications. The originality of this research is to investigate the treatatment wastewater containing RB 5 dye color and biological pollution together for the first time in literature.
