In today's society, as everyone's standard of living improves, the concern for health is also higher and higher, and the health and safety of public places has naturally become the focus of everyone's concern. Library as a large flow of people, dense public places, environmental health is how important, we all have a number in mind. In recent years, chlorine dioxide, a highly effective and safe disinfectant, but in the library environment disinfection in a big way.
Chlorine dioxide, chemical formula ClO₂, is a kind of oxidising disinfectant. It can not only easily deal with bacteria, viruses and other microorganisms, but also remove odours and purify the air. Compared with traditional disinfectants, chlorine dioxide is highly effective in sterilising bacteria at low concentrations and is not harmful to the human body or the environment.
In libraries, chlorine dioxide is mainly used in the following areas:
First, the library air disinfection
library reading room is crowded, air circulation is not very good, bacteria, viruses are easily spread. Chlorine dioxide to air disinfection, you can effectively kill pathogenic microorganisms in the air, reduce the risk of disease transmission. Operation is also simple, put the chlorine dioxide disinfection equipment in a suitable location, set the disinfection time and concentration, can automatically disinfect. Generally speaking, the air disinfection concentration control in 0.2 - 0.3mg/m³ on it, disinfection time, according to the actual situation, 30 minutes to 1 hour can be. Disinfection, chlorine dioxide can quickly diffuse to the entire space, to achieve a full range of dead-end disinfection.

Second, the surface disinfection of books and magazines
library books and magazines borrowed, it is easy to stain bacteria and viruses. The traditional method of wiping disinfection and time-consuming and labour-intensive, but also kill not completely. Chlorine dioxide disinfection is different, it can quickly penetrate into every page of the booklet, the surface of the pathogens are killed. This not only improves the efficiency of disinfection, but also saves labour costs. Disinfection of the surface of the booklet, the use of chlorine dioxide concentration is generally 0.3 - 0.5mg/m³, disinfection time is recommended for about 30 minutes.
Third, the environment deodorisation
library people, there will inevitably be sweat, foot odour these odours. These odours not only affect the reading experience of readers, but also may breed bacteria. Chlorine dioxide deodorant ability is super strong, it can and odour molecules have a chemical reaction, to decompose them into harmless substances, so as to achieve the effect of deodorant. It also eliminates formaldehyde, benzene and other harmful chemicals in the air, making the library environment fresher. Environmental deodorisation, the use of chlorine dioxide concentration can be reduced to 0.1 - 0.2mg/m³, disinfection time adjusted according to the need on the line.

Notes on the use of chlorine dioxide disinfection
Select the right disinfection equipment: there are many types of chlorine dioxide disinfection equipment on the market, according to the actual needs of the library and the size of the space to choose.
Control the disinfection time and concentration: disinfection concentration is too high, too long, may be bad for the human body and the environment. Therefore, before using it, you have to read the manual carefully and operate it according to the recommended parameters.
Maintain ventilation: Although chlorine dioxide is harmless to the human body, but the high concentration may still make people uncomfortable. You have to keep the room ventilated and let the air circulate when disinfecting.
Chlorine dioxide, a highly effective and safe disinfectant, is a great help in the disinfection of library environments. It not only improves the hygiene level of the library, but also provides a more comfortable and safer reading environment for the readers. In the future, with the development of science and technology and the pursuit of healthy life, chlorine dioxide in the field of disinfection of public places in the application of the prospect is certainly broader.
