Embodiment 2
[0046] Use pure water to prepare a mixture containing 5.1g / L p-xylenolphthalein, 7.8g / L Orange G, 50.8g / L sodium sulfite, 41.8g / L allyltrimethylammonium chloride, and 1.75g / L polyvinyl alcohol Chromogenic solution. The chromatographic filter paper was completely soaked in the above mixture for 10 minutes, the filter paper was taken out, and vacuum-dried at 80°C. After drying, cut the filter paper into small pieces of 5×6 mm, and glue it to one end of a 5×80 mm strip-shaped bottom plate to make glutaraldehyde rapid test paper 2#.
Embodiment 3
[0048] Prepared with pure water containing 4.8g / L thymolphthalein, 2,4,6-trinitro-N-(2-nitrophenyl) aniline, 92.2g / L sodium sulfite, 56.8g / L dimethyldiallyl Ammonium chloride, 2.16g / L gum arabic mixed color developing solution. The chromatographic filter paper was completely soaked in the above mixture for 10 minutes, the filter paper was taken out, and vacuum-dried at 80°C. After drying, cut the filter paper into small pieces of 5×6 mm, and glue it to one end of a 5×80 mm strip-shaped bottom plate to make glutaraldehyde rapid test paper 3#.
[0049] Glutaraldehyde determination test paper embodiment 4
[0050] Use pure water to prepare a mixture containing 9.2g / L Alizarin Blue SA, 5.0g / L Alizarin Yellow GG, 32.5g / L Sodium Sulfite, 18.4g / L Benzyltributylammonium Chloride, and 2.16g / L Gum Arabic Chromogenic solution. The chromatographic filter paper was completely soaked in the above mixture for 10 minutes, the filter paper was taken out, and vacuum-dried at 80°C. After dry...
