Determining Nitrite in Drinking Water Based on GB/T 5750-2023 Using UV-Vis Spectrophotometry

Introduction to Nitrite and Its Detection in Drinking Water
Nitrite (NO2?) is an essential intermediate product in the natural nitrogen cycle and is widely present in surface water, groundwater, and some industrial wastewater. It originates from various sources, including agricultural non-point source pollution, wastewater treatment discharge, and residues from its use as a preservative and color fixative in food processing. The health risks associated with nitrite are significant. Once in the human body, nitrite can inhibit the oxygen-carrying capacity of hemoglobin, causing tissue hypoxia, which is particularly harmful to infants. Moreover, in the acidic environment of the stomach, nitrite readily reacts with amines in food to form nitrosamines, which are internationally recognized as potent carcinogens. Long-term intake can increase the risk of developing cancers such as gastric and esophageal cancer. In this blog post, Metash, as one of the high performance analytical lab equipment manufacturers, will share the role of double beam UV visible spectrophotometer in analyzing nitrite in water quality.
