Abstract

The invention discloses a long-acting air pollution control agent which is prepared from colloid A and colloid B. The colloid A and the colloid B are each prepared from a reactant, a carrier and a conditioner. The conditioner comprises a pH conditioner for adjusting the pH value of the colloids and a character conditioner for adjusting the character of the colloids. According to the long-acting air pollution control agent, the pH of the system is kept through a pH buffering solution, it is ensured that the reaction is conducted at a constant speed, and the release speed of chlorine dioxide is more stable; the colloids can be degraded and are free of residues after being used; acid with strong corrosivity is not contained, and the agent is safer to store, transport and use; the air pollution control agent has one purpose of removing air pollutants in micro spaces; by means of isolated package, the colloids do not make contact, the safe storage and transportation of the product are ensured, and the shelf life is greatly prolonged.

Description

technical field [0001] The invention relates to a long-acting air pollution control agent and application thereof, specifically belonging to the field of air pollution control agents. Background technique [0002] In the prior art, the treatment methods for formaldehyde, benzene, xylene and other TVOCs (total volatile organic compounds) in newly decorated interiors, new cars, new furniture and other micro spaces mainly include activated carbon adsorption and photocatalyst degradation. Activated carbon adsorption is slow and saturated, while the release of pollution is continuous for a period of time. Photocatalysts can continue to react, but limited by light intensity, the treatment efficiency is low, and there is pollution to the device. [0003] Chlorine dioxide, as the only safe disinfectant that normally exists in gaseous state, has the excellent characteristics of broad spectrum, safety and high efficiency. However, due to its own instability, it is often used in the ...
