Embodiment 1

[0023] 1) Dissolve 9.00g of potassium iodide, 0.5g of sodium thiosulfate, 0.5g of anhydrous sodium carbonate, and 0.35g of polyvinyl alcohol in purified water and add to 100ml as mother liquor;

[0024] 2) Submerge the test paper completely in the mother liquor, after soaking for 4 minutes, take out the test paper and dry it at 57°C for 22 minutes. After the test paper is completely dry, cut it into a suitable size.

[0025] 3) Immerse the test paper in the peracetic acid disinfectant of different standard concentrations for 1 second and then take it out. After 10s~15s, measure the color of each test paper to make a standard color card of the corresponding color.

Embodiment 2

[0027] Dissolve 8.00g of potassium iodide, 0.6g of sodium thiosulfate, 0.3g of anhydrous sodium carbonate, and 0.15g of polyvinyl alcohol into 100ml of purified water as the mother liquor;

[0028] 2) Submerge the test paper completely in the mother liquor, after soaking for 4 minutes, take out the test paper and dry it at 55°C for 22 minutes. After the test paper is completely dry, cut it into a suitable size.

[0029] 3) Immerse the test paper in the peracetic acid disinfectant of different standard concentrations for 1 second and then take it out. After 10s~15s, measure the color of each test paper to make a standard color card of the corresponding color.

Embodiment 3

[0031] Potassium iodide 10.00g, sodium thiosulfate 0.1g, anhydrous sodium carbonate 0.5g, polyvinyl alcohol 0.25g were dissolved in purified water and added to 100ml as mother liquor;

[0032] 2) Submerge the test paper completely in the mother liquor, after soaking for 3.5 minutes, take out the test paper and dry it at 60°C for 20 minutes. After the test paper is completely dry, cut it into a suitable size.

[0033] 3) Immerse the test paper in the peracetic acid disinfectant of different standard concentrations for 1 second and then take it out. After 10s~15s, measure the color of each test paper to make a standard color card of the corresponding color.

Abstract

The invention relates to a test paper for quickly determining peracetic acid disinfection liquid and a preparation method, and belongs to the field of sanitary disinfection medicines. The test paper is characterized in that the test paper is treated by a solution containing potassium iodide and a stabilizer, and the mass ratio of sodium thiosulfate to sodium carbonate to polyvinyl alcohol in the solution is 1:(0.5 to 5):(0.25 to 2.5). The preparation method comprises the following steps of completely soaking the test paper into mother liquid, soaking for 3 to 5min, fetching out, drying at the temperature of 50 to 70 DEG C, and cutting into proper sizes after the test paper is completely dried, so as to obtain the test paper. The operation method has the advantages that the operation is simple and convenient, the result is clear and visual, the clinical requirement on the concentration and accuracy of the peracetic acid disinfection liquid is completely met, any special technical requirement on an operator is avoided, and the disinfection result of the used peracetic acid disinfection liquid can be visually and quickly evaluated.

Description

technical field [0001] The invention discloses a test paper for rapid determination of peracetic acid disinfectant and a preparation method thereof, which belong to the field of sanitation and disinfection medicines. Background technique [0002] More and more attention has been paid to peracetic acid disinfectant in the disinfection and sterilization of medical equipment, but it will decompose or be continuously consumed during storage and disinfection. It is difficult to guarantee the disinfection effect within a certain processing time. Therefore, medical institutions need to frequently measure the concentration of peracetic acid disinfectant to ensure its disinfection effect. The current national standard method for detecting the concentration of peracetic acid solution is iodometric method. In addition, there are other detection methods including colorimetry, fluorescence method, electrochemical method, spectrophotometry and chromatography. The process of determining t...
