“…The United Nations (UN) has de ned the development goals as a holistic approach focusing on global issues and interrelated on the economy, environment, and society by 2030. Among these goals, the preservation and improvement of the quality of existing water resources is the foremost (Assila et al, 2023). Among the primary issues affecting the deterioration of water quality is dye wastewater originating from different sources (Ssouni et al, 2023).…”

This study investigated the removal of methylene blue (MB) dye from aqueous solutions using raw clay (RC) and expanded clay ball (ECB) with different particle sizes ( = < 200 mesh, and > 200 mesh). A series of studies such as operating time (1 to 90 min), RC and ECB dose (0.1 to 4g/L), pH (2 to 10), mixing speed (60 to 180 rpm) and temperature (20 to 45°C) were additionally conducted through the use of a batch system in order to optimize the process. Additionally, this study investigated the concepts of adsorption kinetics, isotherms, and thermodynamics of MB. RC and ECB were characterized through distinct physical – chemical methods including scanning electron microscopy (SEM), energy dispersive x ray spectrometer (EDAX), Fourier transform infrared spectroscopy (FTIR). The structural changes in the surface morphology of ECB caused it to exhibit lower adsorption capacity than RC. The removal occurred rapidly in the first few minutes. RC (20 min.) reached equilibrium faster than ECB (30 min.). Under optimal conditions, removal efficiencies of > 200 mesh RC, =<200 mesh RC, > 200 mesh ECB, =<200 mesh ECB were obtained as 97.5%, 95.76%, 39.26%, 91.81%, respectively. The results show that the pseudo-second order (PSO), with R2 ranging from 0.69 to 1, and the Langmuir isotherm model, with a good fit for the MB removal for all combinations, are in agreement with the experimental data According to the study results, the process was carried out endothermic and physical.
