Chlorine dioxide tablet disinfector and preparing method thereof

Abstract

The invention discloses a chlorine dioxide tablet disinfector. The chlorine dioxide tablet disinfector is prepared from, by weight, 15 parts to 20 parts of sodium chlorite, 10 parts to 15 parts of stabilizers, 25 parts to 30 parts of activators and 2 parts to 5 parts of instantizers. The stabilizers are one or more kinds of magnesium chloride, anhydrous sodium sulfate and magnesium sulfate. The activators are one or more kinds of sodium hydrogen sulfate, citric acid and tartaric acid. The instantizers are one or more kinds of sodium carbonate, lauryl sodium sulfate and trichloroisocyanuric acid. According to the chlorine dioxide tablet disinfector, the disinfection time is long, chlorine dioxide can be evenly generated for 3 h to 6 h under the indoor temperature condition of 20 DEG C, the concentration is controlled to be about 50 pp to 300 pp, the pH is mild, a drastic reaction is avoided, and the chlorine dioxide tablet disinfector is completely suitable for disinfection in the civilian aspect, the family environment aspect and the like.

Description

technical field [0001] The invention belongs to the technical field of disinfectant preparation, in particular to a chlorine dioxide tablet disinfectant and a preparation method thereof. Background technique [0002] Chlorine dioxide is currently internationally recognized as a safe and broad-spectrum sterilizing, fresh-keeping and deodorizing agent. It is the most ideal substitute for chlorine preparations and has been widely used in developed countries. The United States, Canada, Japan, Western Europe, etc. have approved and recommended chlorine dioxide for disinfection, deodorization, anti-mold, anti-corrosion and preservation of food in food, food processing industry, pharmaceutical industry, hospital, public environment, etc. The World Health Organization (WHO) has also listed chlorine dioxide as an Al grade safe and efficient disinfectant. In order to control the production of "three substances" (teratogenic, carcinogenic, and mutagenic) in drinking water, developed c...

Problems solved by technology

[0004] Preparation of Chlorine Dioxide ClO 2 There are many methods, using sodium chlorite NaClO 2 Adding hydrochloric acid to acidify is a commonly used method, but the by-products of the above reactions will be produced; chemical preparation of chlorine dioxide also uses sodium chlorite NaClO 2 It is produced by acidification, and the difference in pH value has a great influence on the activation effect

The active ingredient in the disinfection process is chlorine dioxide. If the acidity is not enough and the activation time is short, the activation may be incomplete and affect the disinfection effect. Excessive acidity is also not good for water treatment because it will bring many useless or harmful components.

In many analyses, the general iodometric method is commonly used to determine ClO 2 The concentration of ClO can often be 2 - Misdetected as ClO 2 , resulting in ClO 2 The illusion of a high activation rate
