Abstract
The invention relates to a method for preparing a stable sodium chlorite solution, which comprises the following steps of: weighing 95.0-99.9 parts of sodium chlorite solution, 0.01-1.0 part of heavy metal ion complexing agent, 0.01-1.0 part of solution pH value stabilizer, 0-1.0 part of heat-resistant agent and 0-2.0 parts of photoresist; adding into a reactor in sequence, mixing uniformly, and standing still; and finally removing precipitates to obtain the stable sodium chlorite solution product. The method has the advantage of simple process and is safe for production, and the prepared product is stable and has long quality guarantee period.
Description
Technical field
The invention belongs to bleaching agent, disinfectant technical field, be specifically related to a kind of stable sodium chlorite solution's preparation method.
Background technology
Sodium chlorite is a kind of novel, efficient bleaching agent and oxidizing biocide, it also is a kind of industrial wastewater exhaust gas treating agent, often make the sodium chlorite solution in the industry use, its oxidizing potential is between sodium chlorite and hydrogen peroxide, it is a kind of bleaching agent of gentleness, fabric can obtain good whiteness and intensity after its bleaching, this is that other bleaching agents can't be compared, it is is selectively gone or stayed to the cotton fiber commensal, can make the dissolving of lignin and pectic substance and the adipocere of reservation more amount, bleach thick fabrics feel soft, the sodium chlorite solution is applicable to paper pulp and various fiber (cotton, acetate fiber, artificial silk, polypropylene fibre, terylene, polyamide fibres etc.) bleaching is effective.The sodium chlorite solid, highly stable under the normality, but sodium chlorite solution's self stability is relatively poor, causes sodium chlorite solution's factors of instability to have four kinds: light decomposition, thermal decomposition, acid are decomposed and the heavy metal ion catalytic decomposition.
Sodium chlorite solution's unstability has all been brought great inconvenience to its production, transportation, storage, sale and use etc., and has potential safety hazard, if misoperation will cause the slight blast or the personnel that cause to poison and be injured.
Summary of the invention
The present invention is for solving the problems of the prior art, and a kind of stable sodium chlorite solution's preparation method is provided, and its technology is simple, production safety, and product is stable, long shelf-life.
The present invention is achieved by the following technical solutions:
