Abstract
The invention relates to a process for preparing sterilizing and disinfecting algaecide. It is a high efficient and broad-spectrum bactericide with so-called chlorine dioxide. It is starting at the mixing of the sodium chlorite and water with the ratio 1:(4-20 wt),then mix sodium chlorite solution with the complex acid according to the ration (3-5):1wt. Complex acid is comprised of hydrochloric acid 30-35 wt.%,citric acid 30-35 wt.%,hypochlorous acid 30-35 wt.%,among these, the hydrochloric acid concentration is 28-35 wt.%,citric acid concentration is 95-99%,hypochlorous acid concentration is 10-15%;This invention can be used as a disinfection agent in the drinking water, daily necessity and the fishery. It can be use in prevention and cure agent for the fish illness, in the disinfection of the circulated cooling water, in the fresh keeping and disinfection of the food, in the sterilization for the medical treatment equipment, in the waste water treatment etc.
Description
Technical field
The present invention relates to a kind of method for preparing Biocidal algae-killing agent, specifically a kind of method for preparing the chlorine dioxide solvent belongs to disinfectant manufacturing technology field.
Background technology
In the Biocidal algae-killing agent that in sterilization, sterilization and the deodorizing of health care, food sterilization sterilization and anti-corrosive fresh-keeping, drinking-water and aspects such as industrial cycle and waste water treatment, uses at present, it is disinfectant that these great majority adopt chlorine, and the chlorine of generally acknowledging is that optimal disinfection sanitizer is a chlorine dioxide in the disinfectant at present.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of method that Biocidal algae-killing agent is the chlorine dioxide solvent for preparing, and makes that the chlorine dioxide solvent can reach efficiently, the effect of lasting and broad-spectrum sterilization.
The technical solution used in the present invention: a kind of method for preparing Biocidal algae-killing agent, is 1 with the sodium chlorite powder with water ratio by weight: (4～20) fully mix, then with the sodium chlorite solution that mixes and compound acid by weight than being (3～5): 1 mixes and gets final product.
Wherein compound acid is that following substances in percentage by weight mixes: hydrochloric acid 30～35%, citric acid 30～35%, hypochlorous acid 30～35%.
The percent concentration of hydrochloric acid can be 28～35%.
The percent concentration of citric acid can be 95～99%.
Hypochlorous percent concentration can be 10～15%.
The present invention compares with traditional Biocidal algae-killing agent has following beneficial effect:
1, purity height, conversion ratio height: adopt the present invention to adopt the common prepared in reaction generation of sodium chlorite solution and hydrochloric acid, citric acid and hypochlorous acid ClO 2 solution, feed stock conversion can be greater than 90%, make ClO 2 solution get concentration can be greater than 98%.
2, sterilization is efficient, powerful: because the present invention makes the chlorine dioxide solvent, being 1/2 of chlorine gas concentration to the concentration of killing the required chlorine dioxide of heterotroph, is 1/5 of chlorine gas concentration to the concentration of killing the required chlorine dioxide of Escherichia coli in the surface water.
3, sterilization speed is fast, effect is lasting: since chlorine dioxide water-soluble after, substantially not with water generation chemical reaction, do not exist with dimerization or poly state yet, thus chlorine dioxide in water diffusion velocity is very fast, the chlorion in the chlorine dioxide is Cl
+ 1, if want Restore All to become Cl
-1, needs 5 electronics and shift, so chlorine dioxide being a kind of strong oxidizer to have very strong oxidisability, its oxidizing process is lasting, thereby makes bactericidal action lasting.
4, broad-spectrum sterilization: because chlorine dioxide is a kind of broad spectrum type disinfectant, to propagate to such an extent that pathogenic microorganism all has the fine killing effect that gets through water body, except that general bacterium is had the killing effect, also gemma, virus, heterotroph, iron bacteria, sulphate reduction and fungi etc. all there is the fine killing action that gets, and be difficult for developing immunity to drugs, also typhoid fever, hepatitis A, hepatitis B, polio and AIDS virus etc. also had good killing and damping effect.
5, nontoxic, non-stimulated, applied range: after chlorine dioxide is water-soluble, not with water in the organic matter effect generate carcinogens such as haloform, higher mammal cell, sperm and chromosome are not had carcinogenic, teratogenesis, mutagenesis.Its oxidation effectiveness is based on detoxification (oxidation H
2S, SO
2-, CN
-, Mn
2+Deng), to contain the micromolecular compound of dioxygenase gene, these products are harmless to organic oxidative degradation; Chlorine dioxide and phenol reaction do not produce the very big chlorine phthalein phenol of peculiar smell, produce the diversity organohalogen compounds hardly with humus and organic matter reaction thereof; Therefore, have wide range of applications.
