Abstract: PURPOSE: A hydrogen peroxide concentration method and an apparatus using an azeotrope agent are provided to perform a concentration process of hydrogen peroxide stably and cost-efficiently as a driving temperature of the process can be maintained low by using the azeotrope agent. CONSTITUTION: A hydrogen peroxide concentration method using an azeotrope agent comprises steps of: supplying an azeotrope agent that forms un-uniform azeotropic temperature with water about hydrogen peroxide containing water(S10), evaporating water and the azeotrope agent by heating to the azeotropic temperature(S20), collecting the azotrope agent by condensing the evaporated water and the azotrope agent(S30), and re-supplying the collected azeotrope agent to hydrogen peroxide containing water(S40). The azeotrope agent is at least one selected from the group consisting of normal hexane, cyclohexane, benzene, toluene, and xylenes. [Reference numerals] (AA) Start; (BB) End; (S10) Supplying an azeotrope agent that forms non-uniform azeotropic temperature with water relative to hydrogen peroxide containing water; (S20) Evaporating water and the azeotrope agent by heating to the azeotropic temperature; (S30) Collecting the azeotrope agent by condensing the evaporated water and azeotrope agent; (S40) Re-supplying the collected azeotrope agent to hydrogen peroxide containing water
