Abstract
In this research, adsorption experiments were carried out for removal of Basic Blue 41(BB41) dye from an aqueous solution, using coconut fiber particles (CFP) as a low-cost biosorbent. The characteristics of coconut fiber particles weredeterminedwith a scanning electron microscope (FE-SEM) and Fourier Transform Infrared (FTIR) techniques. The effects of initial pH, biosorbentdose, contact time, dye concentration and agitation speed were studied. The Langmuir, Freundlich, Temkin, BET, Dubinin-Radushkevich(D–R) and Harkins–Jura adsorption isotherm models were applied to describe the equilibrium isotherms. The Langmuir isotherm model fit the equilibrium data for the sorbent well, compared to other models. The results indicated that CFP could be employed as an excellent and low-cost sorbent for removal of Basic Blue 41 dye from an aqueous solution.
