Dye removal of cationic dye from aqueous solution through acid functionalized ceramic
In addition to providing advantages, scientific discoveries can pollute the environment in negative ways. The impact of acid treatment on the adsorption ability of earthenware clays to remove malachite green dye (MGD) was studied. This project aims to identify a cost-effective method for cleaning up textile effluent. Adjustments were made to dose, temperature, experiment time, concentration, and stirring speed to maximise dye removal from wastewater. At a pH of 4.5 and a temperature of 27 °C, the highest dye adsorption was observed to be 86%. The Frenundlich adsorption isotherm best matched the process of adsorption; however, the pseudo-second-order kinetic model best explained the kinetics study. The best match of the Elovich adsorption isotherm was reported for acid clays with high R2 values.
