Abstract:

In this study, the adsorption isotherms for removal of Maxilon Golden Yellow GL EC 400% (MGY) dye, which is widely used in industrial facilities from aqueous solutions by using modified clay were investigated. Clay (K0), obtained from the Avanos District of Nevşehir Province, was used as the adsorbent material, modified with ultrasonic sound waves (K1). According to the results obtained, as the contact time increased in the adsorption experiments performed with both clays, the adsorption efficiency also increased. When analyses were made according to the Langmuir and Freundlich Isotherms, it was determined that the adsorption experiments were more suitable for the Langmuir Isotherm. It has been determined that no external energy is required for adsorption. Highest color removal for modified clay (K1); Obtained at pH 4 (99.01%) in 300 minutes and 25 oC. It has been determined that clay, which is abundant in nature, can be used as an alternative important method in the removal of MGY dye with this new modification method.
