Knappa Proba

Knapp’s test

The Knapp test is a method of assessing water quality that is used to determine the presence of contaminants such as bacteria, viruses or chemicals. This method was developed in the 1920s and is still used today to test the quality of drinking water.

To carry out a Knapp test, you need to add a few drops of iodine solution to the water. If the water contains pollutants, then after a while the iodine solution will begin to turn blue. The intensity of the color depends on the amount of pollutants in the water.

One of the main advantages of the Knapp test is its simplicity and accessibility. This method does not require special equipment or knowledge. However, it should be noted that the Knappa test is not an accurate method for determining water quality. It may give false positive results in the presence of certain contaminants, such as iron or copper.

Overall, the Knappa test is a useful tool for assessing the quality of drinking water at home. However, for more accurate results, it is recommended to use more complex analysis methods, such as water analysis for chemical substances or bacteriological analysis.
