Nitrate Sensors FAQs
What is a Nitrate Sensor in water?
Nitrate (NO3-) forms in water when bacteria use dissolved oxygen to oxidize ammonium. … The ZWQ-INO nitrate sensor consists of a silver/silver chloride wire electrode in a custom filling solution. The internal solution is separated from the sample medium by a polymer membrane, which selectively interacts with nitrate ions.
Why do we test for nitrate in water?
Because it dissolves readily in water, nitrate from these sources is usually present at least in low concentrations in drinking-water supplies, regardless of the water source. Utility companies that provide public water supplies test the water for concentrations of nitrate.
How does a Nitrate test work?
Nitrate broth is used to determine the ability of an organism to reduce nitrate (NO3) to nitrite (NO2) using the enzyme nitrate reductase. … If the organism has reduced nitrate to nitrite, the nitrites in the medium will form nitrous acid.
What happens if there is too much nitrate in the water?
Too much nitrogen, as nitrate, in drinking water can be harmful to young infants or young livestock. Excessive nitrate can result in restriction of oxygen transport in the bloodstream.
How do you test nitrate in water?
- Remove the test strip from the packet labeled CL/CO/NA/NI.
- Pick up the strip at the end with no pads.
- Dip the strip in the sample three times and remove without shaking off excess water.
- Hold the test strip level for 2 seconds.
