Abstract
The invention discloses a solid chlorine dioxide release agent, which is prepared from the following components by weight percent: 9-30% of chlorite, 10-50% of dry filling agent, 5-25% of free halogen source, 30-50% of solid acid, and 5-20% of activating accelerator. The solid chlorine dioxide release agent has the following technical effects: 1, HOCl is selected as an oxidant; the ClO2 is oxidized into ClO2 within a required range of the PH value; the solid acid plays a role in regulating the PH value of the reaction mixed solution; 2, the oxidization reaction between HOCl and the ClO2 in the presence of the activating accelerator is high in speed and generates few side reactions and the generated ClO2 is high in purity; the percent conversion in the process of oxidizing ClO2 to generate ClO2 is high; and almost 99% of ClO2 is converted into ClO2 under the condition that the PH value is 3-6; therefore, the residual quantity of the ClO2 in the prepared disinfectant is small; the ClO2 content is high; and the sterilization effect is good (the required CT value is low); and 3, the quality of the solid release agent disclosed by the invention is higher than that of the ClO2 solid release agent prepared by a disproportionation method; and the actual cost of the product is obviously reduced.
Description
Technical field
The present invention relates to a kind of purification disinfectant.
Background technology
The ClO that present domestic most of enterprises produce
2The solid releasing agent is to be that female raw material adds that desiccant, solid acid source etc. are composite with chlorite, employing be that the disproportionation method is prepared from; 1, the principle of disproportionation: after formulation is dissolved in the water, form acid solution, active ingredient ClO
2 -Disproportionation takes place generate ClO
2And Cl
-, i.e. ClO
2 -+ acid → ClO
2+ chloride+other compositions, acid wherein are usually said activator, and this discharges ClO
2Chemical reaction be usually said " priming reaction ".The main reaction equation of priming reaction is: 5ClO
2 -+ 4H
+→ 4ClO
2+ Cl
-+ 2H
2O; 2, the characteristics of disproportionation: ClO
2 -The characteristics of disproportionation are to have a series of side reactions, and reaction velocity is slower.Only activator level very big (be not less than amount of calculation 3～5 times), during the acidity of mixed solution very high (PH≤0.5), just be conducive to above-mentioned main reaction and carry out fully.This moment 5mol ClO
2 -Almost all disproportionation generates 4mol ClO
2With 1mol invalid components Cl
-, the ClO in namely filling a prescription
2 -Conversion ratio becomes ClO
2Conversion ratio near its limiting value 4mol(ClO
2)/5mol (ClO
2 -) * 100%=80%.Therefore, adopt the disproportionation legal system to be equipped with ClO
2The time, material ClO in the prescription
2 -Peak use rate be lower than 80%, and in fact the availability of the prescription produced of most of enterprises at all less than 50%.That is to say ClO in the material
2 -Have at least 20%-50% to lose, be transformed into invalid components.And the solution acidity height of priming reaction, make troubles and cause use cost to increase to practical application.
Summary of the invention
The purpose of this invention is to provide a kind of efficient activating catalytic oxidation chlorine dioxide releasing agent.
Technical scheme of the present invention is that a kind of solid chlorine dioxide releasing agent is made up of following components in weight percentage: chlorite 9～30, dry filler 10～50, free halogen source 5～25, solid acid 30～50, activation promoter 5～20.
Described dry filler is calcium chloride, sodium sulphate, magnesium sulfate or magnesium chloride.
Described free halogen source is lithium hypochlorite, sym-closene or dichlord isocyanurice acid.
Described solid acid is organic acid or inorganic acid.
Described organic acid is tartaric acid, fumaric acid, sulfamic acid or citric acid.
Described inorganic acid is potassium acid sulfate or niter cake.
Described activation promoter is ammonium persulfate, potassium peroxydisulfate or sodium peroxydisulfate.
The present invention has following technique effect, and 1, select for use HOCl as oxidant, HOCl is with ClO in the pH value scope that requires
2 -Be oxidized to ClO
2Solid acid plays the conditioned reaction ph value of mixture; 2, HOCl cooperates activation promoter and ClO
2 -Oxidation reaction speed is fast, and side reaction is few, generates ClO
2Purity height, and oxidation ClO
2 -Generate ClO
2The conversion ratio height; Under the condition of pH value 3～6, almost 99% change into ClO
2, thereby ClO in the thimerosal of preparation
2 -Residual quantity seldom, ClO
2The content height, Disinfection Effect good (required CT value is lower); 3, than adopting the disproportionation legal system to be equipped with ClO
2Solid releasing agent quality height, and the actual use cost of product also significantly reduces.
