Abstract

Commercially available NaY zeolite was modified by H4EDTA to study its characterizations and adsorption properties on chlorine. The mechanisms of chlorine adsorption on NaY and modified NaY zeolites are entirely physical interactions. The modified NaY i.e., [NaY(H4EDTA)] zeolite had a significant enhancement on chlorine adsorption capacity. At 273 K and 0.19 MPa, the maximum chlorine adsorption capacity of the NaY and the NaY(H4EDTA) zeolites were 30.09 and 35.43 %, respectively. The chlorine adsorption capacities and the physico-chemical properties of NaY(H4EDTA) zeolite were studied after eight times adsorption-desorption, suggesting that the NaY(H4EDTA) zeolite can be stably employed in the prolonged cyclic operation. The experimental data show that the chlorine adsorption capacity of the NaY(H4EDTA) increases significantly, because the SiO2/Al2O3 ratio of the NaY zeolite is improved after modified by H4EDTA.
