Abstract

PURPOSE: To obtain an oxygen absorbent having a safe and excellent absorptivity by adhering a metallic halide uniformly on the surface of a metallic powder and regulating its moisture content to less than a given amount.
CONSTITUTION: The surfaces of 100pts.wt. iron powder are coated with 6W 10pts.wt. a metallic halide by mixing the iron powder with a solution of the metallic halide and a tackifier or an alkaline substance, and then dried to a moisture content of 1wt% or less to obtain an oxygen absorbent. In this case, the grain size of the iron powder used is preferably 50 mesh or less, and also the metal of the metallic halide used includes alkali metals, alkaline earth metals, copper, zinc, etc., preferably. The tackifier used includes water-soluble high molecular compounds, e.g., sodium alginate, CMC, etc., and also the alkaline substance used includes the hydroxides, carbonates, etc., of alkali metals or alkaline earth metals.
