Problems solved by technology

The activation rate of chlorite activation method is low (generally about 80%), which is easy to cause waste of sodium chlorite resources
The safety of the chlorine dioxide solid release agent prepared by the hypochlorite activation method is not easy to control, and the loss rate is relatively large. Generally, it can only be stored for one year, which has great instability and risks to the storage and transportation of the chlorine dioxide solid release agent. Security risks
(2) Persulfate method, the activated chlorine dioxide is pure, its release rate and activation rate are greatly affected by temperature and reaction time, the release is slow at room temperature, the activation time is long, and it is difficult to popularize in many fields that require rapid release. In addition, the high cost of the persulfate method is not suitable for promotion

Abstract

The invention relates to the field of environmental purification and disinfectants, in particular to a chlorine dioxide solid releasing agent and a preparation method thereof.The chlorine dioxide solid releasing agent is prepared from the following raw materials in parts by weight:4-26 parts of chlorite,10-65 parts of a bromine-containing inorganic salt activator and 5-20 parts of a passivation stabilizer, wherein a tasteless bromine-containing inorganic compound is used for firstly forming hypobromous acid and then activating sodium chlorite under an acidic condition;hypobromous acid has stronger oxidizing ability than hypochlorous acid and does not produce chloroform, thereby quickly producing high purity and high yield of chlorine dioxide and being less affected by temperature and reaction time;no secondary pollution occurs during use. According to the preparation method of the chlorine dioxide solid releasing agent, chlorine odor is not produced during the production and preparation process, and the production environment and the health of workers are effectively protected;the bromine-containing compound formed during the activation process has higher oxidation performance thanchlorine-containing compound, so the use concentration is lower,the disinfection effect is better and the application range is wider.

Description

technical field [0001] The invention relates to the field of environmental purification and disinfectants, in particular to a chlorine dioxide solid release agent and a preparation method thereof. Background technique [0002] It is well known that chlorine dioxide is recognized by the World Health Organization and FAO as A 1 High-grade disinfectant, because chlorine dioxide belongs to the fourth generation of pollution-free, green disinfectant, it has a wide range of applications, has been paid attention at home and abroad, and the demand is expanding day by day. The existing method of preparing chlorine dioxide solid release agent in China at present mainly uses sodium chlorite as the main agent and hypochlorite to produce and prepare chlorine dioxide solid release agent, and its reaction mechanism is mainly as follows: [0003] 1. Hypochlorite activation method: 2ClO 2 2- +ClO - +2H + =2ClO 2 +Cl - +H 2 o [0004] Internationally, German German Kiro Chemical Comp...
