Removal of Crystal Violate Using Palm (Washingtonia filifera) Fibers from Synthetic Dye Solution

Abstract

The objective to obtain cheap and easily synthesized adsorbents from natural materials is gaining importance day by day. Adsorbents should be environmentally friendly, non-toxic, easily produced, insoluble in water, have a porous structure, a large surface area, and scientifically accepted. In this study, the removal of crystal violet dye from synthetic dyestuff solution was investigated using palm tree (Washingtonia filifera) fibers. As a result of removal studies carried out in unmixed and mixed conditions, the lowest removal efficiency was determined as 18% after 60 minutes for the solution with a crystal violet concentration of 10 mg/L under static conditions. The highest removal efficiencies were reached after 180 minutes for solutions with initial crystal violet concentrations of 5 and 10 mg/L under stationary and mobile operating conditions, respectively. As a result of the study, it was determined that the highest crystal violet removal was 87% after 120 minutes of retention time and the removal complied with the pseudo-second order type 1kinetic model. It was also understood that palm fiber, which is an environmentally advantageous material, can be used in the removal of crystal violet dyestuff.
