PURPOSE: A manufacturing method of a toxic gas purification filter is provided to not only be used as a purpose of air purification in home, office hospital because of high efficiency of contaminant absorption among the air but also be used in ventilation system and reagent cabinet of high density of toxic gas such as laboratory and environmental room because of excellent efficiency of removing acidity substance. CONSTITUTION: A manufacturing method of a toxic gas purification filter comprises the following steps: a manufacturing step of activated charcoal-zeolite mixture by mixing activated charcoal and zeolite to weight ratio of 2:8 - 8:2; a manufacturing step of toxic gas purification filter powder by addling oxidizing agent and basic metallic oxide to the activated charcoal-zeolite mixture; a manufacturing step of toxic gas purification filter dough by addling binder solution to the toxic gas purification filter powder; a manufacturing step of toxic gas purification filter powder from the toxic gas purification filter dough using ventilation; and a plasticity step of the toxic gas purification filter particle. The oxidant is one or more mixtures selected among manganese peroxide potassium, manganese peroxide and lead peroxide. [Reference numerals] (AA) Benzene removal rate; (BB) Unit: % |
