The usage of palm (Washingtonia filifera) fibers for the removal of crystal violet from synthetic dye solution by adsorption

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.

Removal of crystal Violet From Aqueous Solutions by A Newly Developed Adsorbent: İsotherm, Kinetics, and Thermodynamics

“…Adsorbents made from waste rather than traditional activated carbon or materials produced by carbonization are gaining popularity as a result of rising environmental pollution. Adsorbents should also be environmentally friendly, non-toxic, easy to produce, insoluble in water, porous, with a large surface area, and scientifically recognized (Karabaş et al, 2022) In this study, watermelon peels, which are agricultural wastes, were modified with 3 different bases and used as adsorbents to remove crystal violet dye from aqueous solutions. As a result of the modification, the adsorbent with the highest capacity was selected by considering the adsorption capacities of the adsorbents.…”
