Abstract
The invention provides application of pH test paper in testing effective chloride content of a disinfectant containing chloride. The application uses the characteristic that the pH test paper has color differences after the pH test paper tests the pH value of the disinfectant containing the chloride for a certain period, makes a colorimetric card of standard effective chloride content, and integrates the colorimetric card of the standard effective chloride content with a colorimetric card of the pH test paper to make the colorimetric card capable of testing the pH value and the effective chloride content for quickly testing the pH value and the effective chloride content of the disinfectant containing the chloride. The application can be widely applied to testing of the disinfectant of livestock breeding industry, in particular testing of potential of hgdrogen (pH value) and oxidizability (effective chloride content) of the disinfectant containing the chloride of sericulture. The method is simple, quick and direct viewing.
Description
Technical field
The present invention relates to material detection technique field, particularly relate to the purposes that a kind of pH test paper is used to detect effective chloride content of disinfectant containing chloride.This invention is used for fast detecting chlorine-containing disinfectant pH value and available chlorine content with the pH test paper, can be widely used in the detection of the sanitizer of aquaculture, especially for the detection of sericulture chlorine-containing disinfectant potential of hydrogen (pH value) and oxidisability (available chlorine content).
Background technology
China is the country of inventing the sericulture filature in the world the earliest, and the history of silkworm industry is very long.A principal feature of sericulture is a labour concentrated industry.Sericulture obtained significant progress since modern times.Sterilization is an important process in the sericulture process, and the thorough degree of sterilization plays crucial effects to the prevention flacherie, and is therefore particularly important with selection to the understanding of sanitizer characteristic.Selling on the market has various sanitizers, is very different, but sericulture does not also have a kind of chlorine-containing disinfectant characteristic and method for quality of effectively detecting fast at present.The use of defective sanitizer not only brings enormous economic loss to the raiser, and the development of sericulture caused has a strong impact on.
The pH test paper is mainly used in the pH value that detects solution at present, and does not have other purposes.The assay method of effective chloride content of disinfectant containing chloride mainly contains two kinds at present, titrimetry and potassium iodide starch paper detection method, and the titrimetry complex steps, and the potassium iodide starch paper detection method can only be measured available chlorine content separately.In fact, in production practices, usually need to understand simultaneously the potential of hydrogen and the available chlorine content of chlorine-containing disinfectant.But, also do not have a kind of method that can detect chlorine-containing disinfectant potential of hydrogen (pH value) and available chlorine content simultaneously at present.
Summary of the invention
The object of the present invention is to provide a kind of new purposes of pH test paper, be used to detect effective chloride content of disinfectant containing chloride, also do not influence the mensuration of this test paper simultaneously the pH value.The present invention discovers the standard pH test paper after measuring chlorine-containing disinfectant potential of hydrogen certain hour, and this test paper presents different colors, and the difference and the available chlorine content of color have corresponding relation.So make the available chlorine content colorimetric card according to color distortion, integrated with the colorimetric card of pH test paper, reach the purpose that detects potential of hydrogen and available chlorine content simultaneously.
The method for making of colorimetric card that the present invention can detect pH value and available chlorine content simultaneously is as follows:
The chlorine-containing disinfecting agent solution of preparation series of standards gradient concentration dips in the standard pH test paper and to get each concentration solution, places that difference appears in color after 10 minutes, and color is basicly stable after 20 minutes; With this color is foundation, and production standard available chlorine content colorimetric card is integrated with the colorimetric card of pH test paper then, is made into the colorimetric card that can detect pH value and available chlorine content simultaneously.
Chlorine-containing disinfectant is meant sodium hypochlorite, calcium hypochlorite sanitizer, DCCNa sanitizer or TCCA sanitizer etc.
The colorimetric card using method that can detect pH value and available chlorine content simultaneously is as follows:
Measure the pH value of chlorine-containing disinfectant to be measured by classic method, then this test paper was placed 20 minutes,, promptly detect and obtain available chlorine content with above-mentioned standard available chlorine content colorimetric card contrast.
Advantage of the present invention is: can detect the potential of hydrogen (pH value) and the oxidisability (available chlorine content) of chlorine-containing disinfectant simultaneously with traditional standard pH test paper, this method is simple, fast, directly perceived.
