In this research, Zinc sulfide nanoparticles loaded on activated carbon has been synthesized and characterized by a simple procedure and
efficiently has been applied for removal of Methyl Red (MR) from wastewater. For obtaining maximum dye removal the effect of significant
to parameters such as pH 2.0, amount of ZnS nanoparticles on the activated carbon (ZnS-NP-AC), contact time 15 and concentration of MR
on removal percentage of this dye in batch method by one at a time optimization method has been investigated. After the optimization of
variables the experimental data at different concentration of MR was fitted using different models such as Langmuir, Freundlich and
Tempkin. Following the investigation of contact time on the adsorption rate and fitting the obtained results to different kinetic models such
as first order, second order, Elovich and interparticle diffusion model.
