摘要：In this study, a natural zeolite (i.e., Clinoptilolite) was used as bed of a lab scale packed tower. The bed was coated with two transition metals nano-scale particles (i.e., Fe0 and Cu2O). Each coated metal to bed ratio was 4.6 wt.% and the experiments were conducted in air flow of 1 L min-1 and temperature of 200°C. The results showed up to 83.83% of BTX (benzene, toluene and xylene) removal for Fe0 and respectively 32.0 and 56.98% for Cu2O and combined Fe0-Cu2O coated beds. However, the pollutants mineralization/elimination ratio on the combined metals coated bed, with up to 0.83, was greater than the remains which were 0.58 and 0.37 in order for Fe0 and Cu2O coated beds.
