Abstract
Activation methods to improve the adsorption property of natural zeolite by inorganic acid and heat treatments at high temperature were investigated and its function of adsorbing harmful gases was evaluated. The results show that both methods can improve the adsorption property. Natural zeolite which was heat treated for 24 h has an adsorption ratio of 14.67% to H2O in air, which indicates the remarkable improvement of adsorption property. Meanwhile, the adsorption ratios to simulated refrigerator smelling gas such as NH3and H2S after 10 min are 99.00% and 95.20%, respectively.
