Problems solved by technology

Since the quality of activated carbon produced in each batch may vary and the water quality may vary in different seasons or in different periods of the same season, indicating the failure point of activated carbon according to the amount of treated water does not guarantee that the water purifier must meet the requirements within the rated water consumption range, and often May be replaced before failure or failed but not replaced

Embodiment Construction

[0007] (1) The raw materials used in the process are all chemically pure or analytically pure reagents. First dissolve the developer in boiling water, cool to room temperature, then add the iodide main agent under stirring conditions, and after it is completely dissolved, add the pH regulator and the anti-oxidant and anti-mildew stabilizer, stir and mix well.

[0008] (2) Optimized composition ratio range of rapid test agent:

[0009] Contains in 100ml of aqueous solution:

[0010] 1. Iodide main agent: 10g

[0011] 2. Chromogenic agent: 3g

[0012] 3. PH regulator: 2ml of 5% solution

[0013] 4. Antioxidant and mildew stabilizer: 36% solution 2ml

[0014] 5. The rest: water

[0015] Among them: the iodide main agent is KI, NaI, NH, I or their mixtures, and its function is that the iodide reacts with the chlorine in the water to undergo oxidation-reduction reaction to generate free iodine, for example:

[0016] 2KI+Cl 2 →I 2 +2KCL

[0017] The color developer is starch, and its function is:...

Abstract

The invention disclosed a fast testing agent for a water cleaner and a preparation method thereof. The preparation method comprises the following steps of: firstly dissolving a color developing agent in boiling water, cooling the water to room temperature, adding an iodide auxiliary under the condition of stirring for completely dissolving, adding a pH regulating agent and an anti-oxidation moldproof stabilizer, stirring and mixing uniformly to obtain the fast testing agent for the water cleaner. The fast testing agent for the water cleaner disclosed by the invention has the advantages of no toxin, no harmfulness, long storage time, high sensitivity, convenience for testing and the like, thereby providing wider water-cleaner users with a method for simply and conveniently testing the failure of activated carbon in the water cleaner so that the activated carbon can be conveniently and immediately changed.

Description

Technical field [0001] The invention relates to a testing agent for testing whether a water purifier is effective and a preparation method thereof. Background technique [0002] At present, most of the water purifiers sold on the market are activated carbon water purifiers, that is, the main structure of the water purifier is activated carbon filler. The excellent adsorption and filtration performance of activated carbon, especially the adsorption of organic matter in the water, can improve the quality of drinking water. However, the adsorption capacity of activated carbon is limited. If the activated carbon in the water purifier is not replaced and used continuously, it will cause the desorption of harmful substances that have been adsorbed on the activated carbon, and the water quality of the water purifier's outlet water is sometimes even worse than the inlet water quality. [0003] However, when to replace the activated carbon in the water purifier not only troubles users, but ...
