Chlorine dioxide is the acknowledged fourth generation
antimicrobial pesticide, which is a high efficient, safe and
board-spectrum disinfectant. Chorine dioxide is widely applied in
public environment, medical health, food and beverage service
business, food Industry and drinking water treatment in the
developed countries such as U.S.A, Canada, Japan and Western Europe
etc. World Health Organization (WHO) has regarded chlorine dioxide
as AI high-efficiency and safe disinfectant. Environment Protection
Agency (EPA) has approved of chlorine dioxide being an
environmental water treatment chemical. China Ministry of Health
has approved of chlorine dioxide being an high efficient
disinfectant and an food additive. "Disinfection Technical Manual",
which is decreed by China Ministry of Health, has authorized the
application of chlorine dioxide in drinking water. Zhaoguan disinfectant is a kind of chlorine dioxide product which
is unified packing powder. The content and purity of chlorine
dioxide are high in the powder product whose percent conversion of
chlorine dioxide is higher than 96% and the quality of Zhaoguan
disinfectant is beyond reach of other similar products. Zhaoguan
disinfectant was granted patent by State Intellectual Property
Office of P.R. china (Patent Number: ZL99109028.4) Chinese
Nation-wide Chemical Standard Technical Committee Chlorine Dioxide
Working Groups supervise the manufacture of Zhaoguan disinfectant.
The quality of Zhaoguan disinfectant was accepted insurance by the
People's Insurance Company of China (PICC). The Bacterial Disinfection Mechanism of Zhaoguan Disinfectant
Chlorine dioxide releases high efficient and board-spectrum active
oxygen which possess dual adduction. Active oxygen penetrates
membrane of the bacteria cell, destroys the enzyme system, leads to
the disturbance of metabolism and therefore can rapidly kills
bacterium, fungus, virus and spore. The Characteristics of Zhaoguan Disinfectant
1. High efficiency, safety, board spectrum: It is an effective
biocide at concentrations as low as 0.1~0.2 mg/L and toxicological
studies have shown that CLO2'sdisinfection by-product, chlorite,
poses no significant adverse risk to human health. Furthermore, the
product can deodorize, extinguish algae, degrade toxin (heavy
metal, arsenic, phenol and amine), possess flocculation deposition
and eliminate the formation of chlorinated organic compounds.
2. Quality stabilization and action permanence: the bactericidal
power of the product is as five to ten times as chlorine's and the
product unaffected by pH between 6 and 10. Furthermore, its ability
of disinfection is unaffected by hardness and salinity of water.
Disinfection of the product can persist a long time.
3. Stabilizing unified packing product has many advantages: the
convenience of operation: the safety of transport and storage;
avoiding the complex operations when generating chlorine dioxide on
the spot.4. Economic cost: chlorine dioxide of the product is high
(10%) and the product's percent conversion of chlorine dioxide is
higher than 96%. The using cost of the product is similar as the
cost of sodium hypochlorite and the cost is one fourth as the cost
of other chlorine dioxide product. . Zhaoguan disinfectant used in tap-water plant
Preparation of mother liquid: Put one packet product (500g) into
25kg water (note: forbid put water into the solid product),
stirring for 5~10 min and obtain 25kg mother liquid whose
concentration is 2000mgk/L. Dilute the mother liquid as the table: Disinfection object | Dilution ratio ML(kg):Water(kg) | Concentration (mg/L) | Time (min) | Usage method | Seedling | 1:100-1:50 | 10-20 | 5-10 | Spray | Prevention | 1:50-1:33 | 20-30 | 5-10 | Spray | Morbidity | 1:25-1:20 | 40-50 | 5-10 | Spray | Serious illness | 1:20-1:16 | 50-60 | 5-10 | Spray | Seed | 1:20-1:16 | 50-60 | 10-15 | Spray |
Antisepsis and reservation for fruit and vegetable in the process
of storage or transport Preservation object | Dilution ratio ML(kg):Water(kg) | Concentration (mg/L) | Usage method | Fruit | |
