Abstract

목적: 본 발명은 아염소산나트륨과 차아염소산나트륨의 수용액에 무기 또는 유기산을 첨가하여 강산성의 이산화염소의 수용액을 제조하여 유리 이산화염소의 농도가 최대 약 20,000ppm 이하 함유되게 하는데 그 목적이 있다.PURPOSE: The present invention provides an aqueous solution of strong chlorine dioxide by adding an inorganic or organic acid to an aqueous solution of sodium chlorite and sodium hypochlorite so that the concentration of free chlorine dioxide is about 20,000 ppm or less.

구성: 0.1~5.0중량%의 아염소산나트륨, 0.1~1.0중량%의 차아염소산나트륨으로 이루어진 수용액에 무기 또는 유기산을 가하여 강산성의 활성화 유리 이산화염소 수용액을 제조한다.Composition: A strongly acidic activated free chlorine dioxide aqueous solution is prepared by adding an inorganic or organic acid to an aqueous solution consisting of 0.1 to 5.0 wt% sodium chlorite and 0.1 to 1.0 wt% sodium hypochlorite.
