Abstract:

Chlorine dioxide is a highly efficient and safe preservative and has strong antibacterial function. Through the screening of sorbent, passivator and absorbent, seven reaction-type and five absorption-type solid chlorine dioxide antiseptic agents were prepared. Each type of chlorine dioxide antiseptic agent exhibited an excellent antiseptic effect on melon black spot and high stability. The change of additives could effectively control the release rate of chlorine dioxide, which could overcome the disadvantages of short release period, bigger release quantity and uncontrolled release rate of traditional solid chloride dioxide antiseptic agents. The newly developed slow-released solid chloride dioxide preservative will accelerate the application of chlorine dioxide preservatives.

Key words: chlorine dioxide, slow-released, antibacterial effect
