| Summary: | Zeolite NaY prepared by ash from rice husk used for elimination of ammonium from aqueous solutions.
Its performance investigation was compared with natural zeolite granulated formed and powdered
mordenite. Natural zeolite mordenite and prepared Zeolite NaY were characterized by Energy
Dispersive X-ray (EDX), X-ray Diffraction (XRD) and total cation exchange capacity (CEC) was
measured. Measured cation exchange capacity (CEC) of zeolite NaY was 3.15 meq g-1, powdered
mordenite was 1.46 meq g1 and granular mordenite 1.34 meq g-1. Kinetics of adsorption and for the
deletion of NH4+ ions of equilibrium data from aqueous solutions were examined by fitting the
investigational data to various models of reaction order. NH4
+ adsorption on zeolite NaY and mordenite
powder followed Pseudo-second-order reaction kinetically. Compared to all isotherms equations, the
equilibrium pattern fits well to the Langmuir isotherm equation. The adsorption capacity of the monolayer
for powdered mordenite 14.99 mg g- and granular mordenite 13.56 mg g- to be very lower than that
zeolite Y was found 43.25 mg g-. Compared to natural mordenite, it can be concluded that zeolite Y
synthesized from ash husk is a better sorbent for ammonia removal from aqueous solutions predicted to
its higher adsorption capacity and rapid adsorption rate. |
