Solid Phase Extraction of Phenol on Zeolitic Material: Batch Sorption and Column Dynamics
The solid phase extraction of phenol using hydrothermal (CZBFA) and fusion synthesized zeolitic materials (FZBFA) were carried out by batch and column mode. The chemical composition and the functional groups of synthesized zeolitic materials were investigated by XRF and FTIR. The major zeolitic phases and morphology were identified by PXRD and SEM techniques. The isotherms were estimated for the nature of sorption of phenols on sorbents. Thermodynamics parameters exhibited the endothermic nature of sorption. The phenol sequestration is highest for FZBFA as compare to bentonite, mud, and resin sorbents but lower than the activated carbon. Desorption of phenol is highest for BFA with 0.5M NaOH.
