In this study, methylene blue (MB) dye adsorption from the aqueous solution on raw clay samples collected from the Tilkitepe in the east of Lake Van was presented. Batch adsorption studies were conducted to evaluate the effect of various experimental parameters such as pH, contact time and initial concentrations on the removal of MB. The five nonlinear adsorption equations were applied to describe the equilibrium isotherms. Considering the correlation coefficients, the order of the most suitable isotherm models was Sips> Freundlich> Temkin> Dubinin-Radushkevich>Langmuir. From the data applied to the pseudo-first-second order, Elovich and intra-particle diffusion kinetic models, it can be said that the best model describing the kinetics of MB dye adsorption is the pseudo-second order (PSO) kinetic model. The results are shown that Tilkitepe / Van raw clay material could be used as an economical and effective adsorbent for dye removal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
