Abstract

본 발명은 유리 이산화염소를 함유한 안정화 이산화염소 수용액의 제조방법에 관한 것으로, 아염소산나트륨, 무기산, 수산화나트륨 및 인산염만을 사용하여, 수용액 상태에서 직접 반응시켜 유리 이산화염소를 함유한 안정화 이산화염소 수용액을 제조하는 방법을 제공한다.The present invention relates to a method for preparing a stabilized chlorine dioxide aqueous solution containing free chlorine dioxide, using only sodium chlorite, inorganic acid, sodium hydroxide and phosphate to react directly in an aqueous solution state to stabilize the chlorine dioxide solution containing free chlorine dioxide. It provides a method of manufacturing.

본 발명에 따른 합성방법은 수산화나트륨, 인산염만으로 이루어진 안정화 용액으로, 일단계 반응으로 합성으로 짧은 시간 내에 끝나고, 그 안정성이 더욱 향상된 종래의 방법에 비하여 공정이 간편하고 더욱 안정화된 새로운 이산화염소의 제조방법이다.Synthesis method according to the present invention is a stabilization solution consisting of sodium hydroxide, phosphate only, the synthesis in a one-step reaction in a short time, the production of new chlorine dioxide is simpler and more stable than the conventional method with improved stability Way.
