Abstract

Volatile organic compounds (VOCs) are in categories of mankind and environmentally harmful materials. Some of VOCS are also carcinogenic and mutagen. Because of expanded application of these compounds as various domestic and industrial usages, prevention of environmental contamination of these compounds is a substantial issue. In this study, the effect of zero-valent iron nanoparticles application on a natural zeolite media, for VOCS removal efficiency was surveyed.The Clinoptilolite zeolite after acidic amendment was used as a bed and coated with zero-valent iron nanoparticles. The particles were in size of 30-60 nm. The BTX compounds including BENZENE, TOLUENE and XYLENEs were applied as indices for VOCS pollutants. The obtained results showed a significant difference in removal of the pollutants whether by use of iron nanoparticles or not (P-v= 0.008). The average removal efficiency without iron nanoparticles application was %43.31±24.84, and by application of the nanoparticles it was %83.83±1.3. Application of iron nanoparticles caused more complete decomposition of the pollutants up to 57.82%. According to the results, iron nanoparticles increased the VOCS removal efficiency of the zeolite and led to decomposing more amounts of pollutants in a unit volume of the zeolite. The amount of pollutants which completely decomposed to CO2 is also increased.
