How To Test Ammonia In Water
The method of measuring ammonia in water
The ammonia content in water is quite important to people's livelihood, so the method of measuring ammonia in water is indispensable.
To measure ammonia in water, you should first prepare all kinds of utensils. Glassware that needs to be cleaned, such as a measuring cylinder with accurate capacity, a triangular bottle with a plug, etc.; also need all kinds of reagents, such as Nasser's reagent, etc., this reagent is crucial in the process of measuring ammonia.
When taking water samples, be careful. Choose a representative office of the water source and take an appropriate amount of water samples with clean utensils to prevent them from being contaminated by other things. After the water sample is collected, measure it quickly. If it cannot be tested immediately, it should be properly stored according to law to prevent the composition of ammonia from changing.
The method of measurement is as follows: First measure the water sample in the triangular bottle, and slowly add the Nauert reagent in proportion. Be careful not to splash the reagent when adding. After adding, shake the triangular bottle gently to make the reagent fully mixed with the water sample. After a while, observe the color change. If the water contains ammonia, the solution is yellow-brown in different shades. Standard ammonia solutions can be prepared, and a series of color standards can be obtained by operating according to the same method. By comparing the color of the water sample with the standard color, the approximate content of ammonia in the water can be known.
Another method can borrow a sophisticated instrument. If a spectrophotometer is used, place the treated water sample in the instrument according to its operating rules. Adjust to the appropriate wavelength and measure its absorbance. According to the standard curve drawn in advance, the content of ammonia in the water is inferred from the absorbance. This instrument has high accuracy, but the operation needs to be in accordance with the specifications, and the instrument needs to be properly maintained.
Measuring the content of ammonia in water is related to water quality, and is of great significance for human drinking, agricultural irrigation, aquaculture, etc. Therefore, those who use this method should be cautious to obtain accurate numbers.
