Nitrate Test Kit based on Brucine method. Manufacturer and supplier in Mumbai, Kandla, Chennai, Vizag, Kolkata, Fujairah, Dubai, Sharjah.
Significance and Use:
Nitrate ions are present in trace amounts in surface water and in higher levels in some groundwater. Nitrate is found only in small quantities in domestic wastewater but can reach higher concentration (up to 30 mg/L as nitrogen) in the outflow of nitrifying biological treatment plants. Excessive amounts can contribute to methaemoglobinemia: infant death and adult illness. In order to prevent this, a 10 mg/L limit (as nitrogen) has been imposed on drinking water.
NOTE: mg/L is equivalent to ppm (parts per million).
Chemical Reaction:
Nitrates are reduced to nitrites in the presence of Cadmium. The nitrites thus produced react with the reagent to yield an orange compound. The amount of color developed is proportional to the concentration of nitrate present in the aqueous sample.
Safety Data Sheets:
The chemicals contained in this kit may be hazardous if improperly handled. Read the relevant Safety Data Sheet before performing this test.
This method gives results in the range of 0.05 to 0.8 mg per litre nitrate nitrogen.
