Embodiment Construction

[0016] In order to make the technical means, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0017] An embodiment of the detection reagent of the present invention is:

[0018] The invention discloses a detection test paper for detecting residual chlorine, pH value and total alkalinity in water. The polystyrene sheet 1 is used as a substrate, and the chromatographic test paper is used as a color test paper block. The chromatography test paper is pasted on the front end of the polystyrene sheet 1. The polystyrene sheet 1 has a length of 6 cm and a width of 0.3 cm. The area of ​​the chromatography test paper is 0.01 cm 2 . There are three chromatographic test papers, which are respectively residual chlorine color test paper block 2, pH value color test paper block 3 and total alkalinity color test paper block 4; two adjacent chromatography test papers are sepa...

Abstract

The invention relates to test paper for detecting the residual chlorine, pH value and total alkalinity in water. The test paper comprises a substrate and coloration test paper pieces bonded to one end of the substrate; the three coloration test paper pieces comprise a residual chlorine coloration test paper piece, a pH value of coloration test paper piece and a total alkalinity coloration test piece; adjacent pieces have a 1-3 cm distance; the chlorine coloration test paper piece is impregnated with a absolute ethyl alcohol solution of benzophenone thiosulfate with concentration of 0.1-1.9 g / L; the pH value coloration test paper piece is impregnated by a pH value coloration mixed solution containing phenol red and bromothymol blue with concentration ranged from 0.01 to 1 g / L an water-alcohol of surfactant with concentration of 0.1-10 g / L and; and the total alkalinity coloration test paper piece is impregnated with a total alkalinity coloration mixed solution containing water-alcohol of phenol red or bromothymol blue with concentration of 0.1-5 g / L. The test paper provided by the invention has the advantages of rapidness, simpleness, high sensitivity simultaneous detection of residual chlorine, pH value and total alkalinity in water.

Description

technical field [0001] The invention relates to a detection test paper, in particular to a detection test paper for detecting residual chlorine, pH value and total alkalinity in water. technical background [0002] Swimming is a popular sport that people like very much in summer, but while exercising, we also need to monitor the water quality in the swimming pool, otherwise it will cause harm to people's health. The most basic monitoring indicators in swimming pool water quality are: residual chlorine, pH and total alkalinity. Residual chlorine refers to the content of free chlorine in swimming pool water that can kill bacteria. Total Alkalinity refers to the CO in swimming pool water 3 -2 and HCO 3 -1 sum of values. Previous tests generally used analytical instruments or chemical analysis methods. These methods all require analytical laboratories, analysts, and analytical equipment, and have more restrictive conditions. For swimming pool users who need daily maintena...
