摘要：<p>PURPOSE:To effectively clean low-concn. contaminated air at a low running cost by bringing the low-concn. contaminated air into contact with an air purifying agent deposited with potassium permanganate while regulating spatial velocity SV value to specified value or below. CONSTITUTION:A purifying agent for air in which KMnO4 is deposited on an inorganic carrier is obtained by adding KMnO4 to the inorganic carrier, for example such as activated alumina, slaked lime, colloidal silica and sepiolite and kneading the mixture together with a small amount of water and molding it. This purifying agent for air is packed in a column and contaminated air incorporating contamination gas such as H2S, SOx, phosphine and arsine at low concn. is passed through the column so that spatial velocity SV value is regulated to <=5,000 and the contaminated gas is removed.</p>
