Currently, the research and development of chlorine dioxide generating device and reagent combination are also concerned, conventional means can be divided into use and set
Standby scene is relatively large to produce and adds water priming reaction to produce two kinds the medicament being formulated.Relatively large two are prepared using equipment
Chlorine monoxid is mixed in a certain ratio with hydrochloric acid and sodium chlorite and generates gas；Reagent combination adds water activation to use chlorite
It is mixed with ackd salt, generates chlorine dioxide in aqueous solution, you can used.The application of above two method is more wide at present
It is general.The former is mainly used for the medium-and-large-sized enterprise such as waterworks, paper mill, and the latter is then used to cultivate disinfection, field of food preservation.So
And due to both using chlorite to be used as raw material, costly, and the product that hydrochloric acid and sodium chlorite react contains price
There is chlorine by-product, chloroform noxious material is will produce in processing tap water process, to lose chlorine dioxide treatment certainly
The superiority of water.And if reagent combination plus water activate, and have chlorine dioxide and overflow and spread in air, not only cause
Waste, and sharp aroma is difficult to endure, and in gained ClO 2 solution product, also contains the Toxics such as remaining chlorite
Matter, while chlorite can react in storage with ackd salt and medicament is caused to fail.
