NITROGEN OXIDE REMOVING AGENT AND NITROGEN OXIDE REMOVING BODY USING SAID AGENT

摘要

PURPOSE:To enhance the decomposing and removing ability by forming the nitrogen oxide removing agent with a nitrogen oxide decomposing substance such as sulfamic acid and/or a nitrogen oxide collecting substance such as Fe(II) nitrilotriacetate chelate compd. CONSTITUTION:One or more nitrogen oxide decomposing substance and/or a nitrogen oxide collecting substances are incorporated into a hydrophilic high molecular substance or activated carbon to produce the nitrogen oxide removing body. Sulfamic acid, ammonium sulfamate, sodium sulfamate, urea, etc., can be used as the nitrogen oxide decomposing substance, and Fe(II) nitrilotriacetate chelate compd., Fe(II) ethylenediamine tetraacetate chelate compd., etc., can be exemplified as the nitrogen oxide collecting substance. Besides, polyvinyl alcohol, polyacrylic acid, the alkali metal salt of polyacrylic acid, etc., can be exemplified as the hydrophilic high molecular substance.
