Abstract
목적:본 발명은 인산염, 탄산염, 과산화수소로만 구성된 간단하고도 경제적인 수용액계에 무기산 또는 유기산의 강산성하에서 이산화염소를 pH 1~4될 때까지 흡수시켜 강산성의 고순도 유리 이산화염소의 수용액의 제조방법으로서 유리 이산화염소의 농도가 최대 약 20000ppm 이하의 범위인 고순도 유리 이산화염소 수용액의 제조방법을 제공하는데 그 목적이 있다.PURPOSE: The present invention provides a simple and economical aqueous solution composed only of phosphate, carbonate and hydrogen peroxide, which absorbs chlorine dioxide at pH 1-4 under strong acidity of inorganic or organic acid, thereby producing an aqueous solution of strongly acidic high purity free chlorine dioxide It is an object of the present invention to provide a method for preparing a high purity free chlorine dioxide aqueous solution in which the concentration of free chlorine dioxide is in the range of up to about 20000 ppm.
구성:활성화 이산화염소 수용액을 제조함에 있어서, 1.0~10.0중량%의 탄산나트륨, 0.1~2.0중량%의 제이인산나트륨, 0.1~3.0중량%의 과산화수소로 이루어진 수용액계에 무기산 또는 유기산의 강산성하에서 이산화염소를 pH 1~4될 때까지 흡수시켜 강산성의 고순도 유리 이산화염소 수용액을 얻는다.Composition: In preparing an activated chlorine dioxide aqueous solution, chlorine dioxide was added to an aqueous solution of 1.0 to 10.0 wt% sodium carbonate, 0.1 to 2.0 wt% sodium diphosphate, and 0.1 to 3.0 wt% hydrogen peroxide under strong acidity of inorganic or organic acid. Absorb until pH 1-4 to obtain a strongly acidic high purity free chlorine dioxide aqueous solution.
