Water Nitrate and Nitrite by UV Vis Test
The water nitrate and nitrite analysis using ultraviolet-visible (UV-Vis) spectrophotometry is a critical tool in ensuring the safety of drinking water supplies. This method, adhering to international standards such as ISO 7405 and ASTM D3916, provides accurate quantitative measurements of nitrate (NO₃⁻) and nitrite (NO₂⁻) in water samples. This service is particularly important for regulatory compliance with the Safe Drinking Water Act (SDWA) and other global standards.
Our laboratory utilizes state-of-the-art UV-Vis spectrophotometers that offer precision down to parts per billion levels, ensuring reliable detection of nitrate and nitrite in complex matrices. Sample preparation involves dilution and filtration steps tailored to the specific characteristics of the water source. This method is widely recognized for its simplicity, reproducibility, and minimal interference from other ions present in the sample.
Understanding the significance of nitrate and nitrite levels in water is crucial given their potential impact on public health. Nitrate, when consumed through contaminated drinking water or ingested as nitrogen dioxide (NO₂), can lead to methemoglobinemia ('blue baby syndrome') in infants. Nitrite itself can form carcinogenic compounds under certain conditions. Therefore, regular monitoring of these parameters is essential for maintaining water quality standards.
The UV-Vis technique operates by measuring the absorption spectrum of nitrate and nitrite ions within a specific wavelength range (typically around 205 nm). The absorbance values are then used to calculate concentrations based on calibration curves prepared with known standard solutions. This approach ensures accurate quantification even in low concentration ranges, which is particularly important for detecting sub-ppt levels that may not be evident using other methods.
A key advantage of this method lies in its ability to differentiate between nitrate and nitrite species accurately. This differentiation allows us to provide precise information regarding both forms of nitrogen present in the sample, helping stakeholders make informed decisions about treatment processes or source water selection.
