- Abstract
Malachite green adsorption characteristics of magnetic beads have been investigated by batch and column methods. The maximum removal percentage of malachite green (93.9 %) was obtained at pH 7-8. The Langmuir and Freundlich isotherms were used to investigate the adsorption equilibrium. It was found that the Freundlich model provides the best correlation with the equilibrium. In the column method, the BDST model was used to obtain an empirical relationship for the design of the adsorption column. The characterization of the prepared magnetic beads has been accomplished by FTIR, SEM, and XRD measurements.
