摘要: Nitrogen oxide gas (NOx), consisting of nitrogen monoxide (NO) and dioxide (NO2), at a low concentration corresponding to that on roads as result exhaust from automobiles, was supplied for 25 days through laboratory-scale biofilter packed with soil packing material. The removal efficiency NO2 by almost 100%, the NO 60% average 86% maximum. By using γ-irradiated material, completely removed mainly adsorption onto or absorption into However, in sterilized only 20%, suggesting microbiologically under aerobic conditions.
