[0049] (2) Preparation of A solution: A solution containing mass concentration is 4% adsorbent allyl methacrylate crosslinked polymer ( E200), 16% color indicator (histidine methyl ester), 15% catalyst (citric acid), and 5% suspending dispersant (sodium isooctylbenzenesulfonate).

[0050] The preparation method is: weigh 20g allyl methacrylate crosslinked polymer ( E200), 80g histidine methyl ester, 75g citric acid, 25g sodium isooctylbenzenesulfonate, and dilute to 500mL with deionized water. Stir well.

[0051] (3) Dip the plain paper prepared in (1) into the solution A and fully infiltrate it. Dry at 90°C.

[0052] (4) Preparation of B solution: ...

Embodiment 3

[0058] (1) Preparation of plain paper: prepare a fixative (carboxymethyl cellulose) solution with a mass concentration of 0.5%.

[0059] Preparation method: Weigh 5g carboxymethyl cellulose and dissolve it in deionized water, and dilute to 1000mL. Cut the filter paper into a size of 10cm×10cm, soak it in the solution, fully soak it, and dry it at 85°C.

[0060] (2) Preparation of A solution: A solution containing a mass concentration of 2% adsorbent (white carbon black), 10% color indicator (glycine ethyl ester and L-histidine methyl ester combination), 3% catalyst (p-toluenesulfonic acid), 0.1% suspending dispersant (sodium dodecylbenzenesulfonate).

[0061] The preparation method is: weigh 10g white carbon black, 40g glycine ethyl ester, 10g L-histidine methyl ester, 15g p-toluenesulfonic acid, 0.5g sodium dodecylbenzenesulfonate, and dilute to 500mL with deionized water . Stir well.

Abstract

The invention discloses test paper for rapidly detecting concentration of an o-phthalaldehyde disinfectant and a preparation method and application of the test paper. The test paper comprises a substrate and filter paper, wherein the filter paper is stuck to the substrate and is dipped with a fixative solution, a solution A and a solution B, wherein the solution A comprises the following ingredients: 0.2% to 4% of adsorbent, 0.2% to 16% of colored indicator, 0.1% to 15% of water-soluble solid organic acid and 0.02% to 5% of suspension dispersant; the solution B comprises the following ingredients: 0.2% to 6% of adsorbent, 0.1% to 6% of suspension dispersant and 0.2% to 10% of adhesive aqueous solution. The test paper for rapidly detecting the concentration of the o-phthalaldehyde disinfectant, provided by the invention, can be used for rapidly and accurately detecting the content of o-phthalaldehyde. The test paper facilitates that medical staff can monitor the concentration of o-phthalaldehyde at any time, and the operation is simple and rapid, so that the safety of disinfection effect of medical appliances is guaranteed.

Description

technical field [0001] The invention relates to the field of chemical detection, in particular to a test paper for rapid detection of the concentration of o-phthalaldehyde disinfectant and its preparation method and application. Background technique [0002] As a disinfectant, o-phthalaldehyde has the advantages of broad bactericidal spectrum, high efficiency, non-corrosiveness, and non-irritation. It is widely used in the disinfection of medical equipment such as hospital endoscopy, dialysis, and anesthesia equipment that require low-temperature and high-level disinfection. During the process of disinfecting medical devices, the concentration of o-phthalaldehyde in the continuously used disinfectant will gradually decrease. The concentration of o-phthalaldehyde is the key to ensure the effect of sterilization and disinfection. When the concentration is lower than 0.3%, the purpose of disinfection cannot be achieved. In practical applications, the concentration of o-phthala...
