Abstract

The invention discloses a chlorine dioxide solution spray and a preparation method thereof. The chlorine dioxide solution spray is prepared from, by mass, 10-20 parts of sodium chlorite, 5-10 parts ofan acidic activator, 10-20 parts of a stabilizer and 80-90 parts of water, and the preparation method comprises the following steps: adding the sodium chlorite into the water to be stirred and dissolved to obtain an aqueous solution; adding the acidic activator into the aqueous solution for mixing; adding the stabilizer into the aqueous solution for mixing, and adjusting the pH value of the aqueous solution to a predetermined fixed value to obtain a chlorine dioxide mixed solution; filtering and removing precipitates of the chlorine dioxide mixed solution, and diluting. According to the invention, one or more specific alkaline metal compound stabilizers are added to adjust the pH value of the chlorine dioxide reaction system and reduce the salt concentration in the solution; therefore, the service life of the chlorine dioxide solution spray is prolonged, and the problem that powder or white spots are left after drying when chlorine dioxide is used as a surface disinfectant and spray is solved.

Description

technical field [0001] The invention relates to the field of disinfection and sterilization products, in particular to a chlorine dioxide solution spray and a preparation method thereof. Background technique [0002] ClO 2 It is a yellow-green to orange-yellow gas, and is internationally recognized as a safe and non-toxic green disinfectant. As far as oxidative biocides are concerned, chlorine dioxide is a highly selective oxidizing agent. Ozone and chlorine are more reactive than chlorine dioxide and can oxidize most organic compounds. However, chlorine dioxide only interacts with reducing sulfides, secondary amines, tertiary amines, and other strongly reducing and reactive organic compounds. Chlorine dioxide therefore leads to more stable reaction products at much lower levels than using chlorine and ozone. In the case of high organic matter, the use of chlorine dioxide in moderate amounts is more effective than ozone and chlorine due to its selectivity. From the comp...
