Abstract

The invention relates to a reagent, a device and a method for purification, and in particular, relates to a reagent, a device and a method for purification by generating chlorine dioxide. The purifying agent comprises a first component and a second component which exist independently, the first component comprises chlorite or a chlorite aqueous solution, and the second component comprises an active agent, a catalyst and an activity inhibitor; the molar ratio of chlorite ions in the chlorite or chlorite aqueous solution to hydrogen ions in the active agent to iodide ions in the catalyst to hydroxide radicals generated by the activity inhibitor is 1:(0.3-3):(0.04-0.4):(0.05-0.3). The purifying agent can be rapidly prepared under the condition of ensuring controllable safe exposure concentration of a human body and stably release chlorine dioxide gas for a long time within a certain period, so that the chlorine dioxide gas can be prepared and released instantly and stably for a long time.

Description

technical field [0001] The present application relates to reagents, devices and methods for purification, in particular to reagents, devices and methods for purification by generating chlorine dioxide. Background technique [0002] Chlorine dioxide (ClO 2 ) has strong oxidizing properties, and its bactericidal ability is 5 times that of chlorine and more than 50 times that of sodium hypochlorite. It has good killing and inhibiting effects on bacteria, fungi, viruses, spores, etc., and is often used for drinking water and air disinfection. [0003] However, when chlorine dioxide gas is used as an environmental disinfectant, on the one hand, it needs to maintain a certain concentration continuously, and on the other hand, it is necessary to ensure the safety of people or animals in the same space. The Occupational Safety and Health Administration (OSHA) of the United States stipulates that the daily 8-hour adult occupational safety exposure concentration of chlorine dioxide i...
