摘要

PROBLEM TO BE SOLVED: To provide an absorbent for nitrogen oxide and sulfur oxide which can remove the nitrogen oxide and the sulfur oxide by a low running cost. SOLUTION: 200g zeolite (the specific surface area is 400m<2> /g and the shape is spherical) is placed in a closed container with a vol. of 1,000ml and 50g aminopropyltrimethoxysilane in a petri dish are placed in a closed container and is allowed to stand at room temp. for 24hr to obtain an absorbent in which the silane compel. is bonded on the zeolite by a siloxane bonding.
