چکیده
|
This study investigates the adsorption of crystal violet (cv) dye from aqueous solutions using original and modified periwinkle-clay rooftile composites. the objective is to explore the efficacy of periwinkle-clay rooftile composite as a catalyst for treating simulated textile wastewater containing crystal violet dye. percentage dye removal of crystal violet from the simulated textile wastewater was examined using both modified and unmodified catalysts. results indicate that cv removal increased with contact time, adsorbent dose, temperature, and ionic strength, while decreasing with initial dye concentration above 80 mg/l. the ph range of 6-11 was found to be optimal for cv dye removal. adsorption equilibrium for cv dye by periwinkle-clay rooftile (both modified and unmodified) was achieved within 105 minutes, with a removal efficacy of up to 98% for both types of catalyst. the pseudo-second-order kinetic model provided the best fit for describing sorption kinetics for both modified and unmodified catalysts. in addition, the freundlich isotherm model was suitable for describing adsorption isotherms for the modified catalyst, while temkin isotherm model was appropriate for the unmodified catalyst. this study offers valuable insights into the potential application of periwinkle-clay rooftile composites for wastewater treatment in the textile industry.
