Olcayto Keskinkan,Buket Karabaş,Bülent Sarı,Behzat Balcı,Hasan Kıvanç Yeşiltaş 한국섬유공학회 2023 Fibers and polymers Vol.24 No.10
This is the first study to show the use of fibers from the Washingtonia filifera palm tree as an adsorbent for the removal of Crystal Violet (CV) dyestuffs from aqueous solutions by adsorption. The research on new materials to prevent the contamination of pollutants is of great importance. CV is a dye that is known to have toxic and carcinogenic effects and is used in many industries. In this study, the effects of parameters such as initial adsorbate concentration, adsorbent dose, and pH on the adsorption efficiency were investigated. The highest removal efficiency was 95.55% and the maximum adsorption capacity was found to be 85.91 mg/g. The maximum adsorption capacity of the fibers used reached a pH of 8. The BET surface area of the adsorbent was 4.1484 m2/g and the average pore width 6.8563 nm. The average pore volume was 0.00413 cm3/g for mesopores and 0.00017 cm3/g for micropores. Stegmata structures, also called silica bodies, were observed in SEM images. Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich (D-R) isotherms were studied. The Temkin isotherm (R2=0.9692) best explained the results in the stirring experiments. The Freundlich isotherm (R2=0.9643) best explained the stationary phase systems without stirring. It was determined that the equation that best explained the dye removal kinetics was the pseudo-second-order kinetic model.
