3. Convenient Packs: small size, lightweight and convenience for carrying.

3. Operation

1. Take out tube, measure about 15ml water sample into tube, add one pack of reagent I and close tube with lid, then smoothly shake up.

2. After 2 minutes, add reagent II, close the tube and shake up again, waiting for about 15 minutes.

3. Open the tube and put tube above the color chart, viewing sample from top to bottom and comparing sample color with color chart, same color result is showing proportion of ammonia nitrogen.

Note: Temperature of testing Environment: 10-30°C

4. Fields of Application

Household drinking water and water sources, surface water, aquiculture water, irrigation water, seawater, household and industrial wastewater and etc

Various industries involving large amount of water require frequent water testing, and the controlling of water quality to meet the different standards. In the case of water deterioration, water tests must be conducted immediately, so measures can be taken accordingly, to prevent serious consequences.

The testing packs are very convenient for on site operation, and can satisfactorily meet the requirements in various industries.

5. Development Background

Sources of Ammonia Nitrogen Pollution:

Major ammonia nitrogen pollution usually comes from the biological decomposers of organic chemicals in household wastewater, industrial wastes such as charring wastes and fertilizer wastes, and agriculture wastes such as cropland wastes, aquiculture wastes, etc. In anaerobic environment, with the presence of nitrites, organic materials can be reduced through micro-bioprocess to form ammonia. In aerobic environment, ammonia in water can be converted to form nitrite or nitrate.

Hazard Caused by Ammonia Nitrogen:

Ammonia nitrogen usually presents in water in the forms of dissociative nitrogen or ammonium ions. Dissociative nitrogen is ten times more toxic than ammonium ions, and the toxicity increases with the alkalinity in water. The increasing temperature and pH will increase the toxicity of ammonia nitrogen. Aquatic organisms are very sensitive to the presence of ammonia nitrogen, which can cause anemia, chronic poisoning, in appetency, gill diseases, respiratory difficulties, restlessness or even sudden death of fishes, and shrimps. Ammonia nitrogen is also an important nutrient for aquatic plants. If large amount of ammonia nitrogen enters lakes, reservoirs, or water bays, aquatic organisms will be activated to reproduce, causing eutrophication and other serious consequences. Therefore it is essential to monitor the concentration of ammonia nitrogen in water, and assess the conditions of pollution and self-purification in water.
