Assessment of the Efficiency of Crushed Ceramics in Adsorbing Methyl Orange Dye from Aqueous Solutions

This study evaluates the efficiency of crushed ceramic as an adsorbent for the removal of methyl orange dye from aqueous solutions. Various parameters influencing the adsorption process were examined, including pH, contact time, adsorbent dosage, initial dye concentration, and temperature. The adsorption process was optimized at a pH of 2.0, achieving a maximum removal efficiency of 99.31%. Adsorption equilibrium was reached after 90 minutes, with the adsorption capacity increasing with higher initial dye concentrations. The adsorption isotherms were analyzed using Langmuir and Freundlich models, with the Freundlich model providing a better fit for the equilibrium data (N = 2.724). Kinetic studies indicated that the adsorption followed a pseudosecond- order model, suggesting that the rate-limiting step involves chemisorption. The Langmuir maximum adsorption capacity (Qmax) was determined to be 22.31 mg/g, while the Freundlich constant (KF) was 2.026. The results demonstrate that crushed ceramics are a promising low-cost adsorbent for the efficient removal of methyl orange from contaminated water, offering potential applications in wastewater treatment. The study also underscores the importance of utilizing appropriate kinetic and isotherm models for accurately predicting adsorption behavior and optimizing operational conditions.
