Nitrite in Nature: Determination with Polymeric Materials

Abstract

Nitrogen compounds being important for the vital activities of living things are produced by the nitrification process and occurred spontaneously in the nitrogen cycle. Human vital activities are also responsible for the extra nitrogen released into the atmosphere. So, both human and environmental healths are negatively affected by the increasing nitrate and nitrate amounts in water and soil. For this reason, it is aimed to ensure regular control of nitrates and nitrites at certain levels in order to protect the universe and all living things. Their precise and selective determination by various methods is very important. Their determinations can usually be made by using electrochemical, spectrophotometric, chromatographic and titrimetric methods. Nowadays instead of these techniques, sensors are preferred in determining nitrate and nitrite due to their easy, fast, selective and sensitive application properties. Furthermore, polymeric materials have shown great promise for different sensing applications such as gas, humidity, explosive and water pollutants. Sensors, which are developed by polymerization, have very high quality for the determination of nitrite. The highly sensitive results of optical and electrochemical sensors attract the attention of researchers. In this review, different detection methods for nitrite ions and various studies on the preparation of polymeric sensors that can selectively capture the nitrite ions in complex matrices are examined.

Recent Advances in Chemical Sensors for Soil Analysis: A Review

“…Changes in nutrient concentrations in inflow and outflow provided information about the uptake of ions by plants and provided feedback about the nutrient needs of plants to be met. Selected applications of polymeric materials for nitrite assessment in nature, with particular attention on sensing materials' compositions and performances, are overviewed by Yenil and Yemiş in [57].…”

A preliminary metagenomics study of bacteria present in the dirt of Swiftlet farmhouses based on nitrite levels in edible bird's nest on Sumatera Island, Indonesia

“…The first stage is the formation of nitrite (NO 2 ), and the second stage is nitration, that is, the conversion from nitrite into nitrate form (NO 3 ) [23,24]. A study on Swiftlet feces and air conditions using 16S rRNA in an SFH of Sarawak, Malaysia, detected the gram-positive pathogenic bacteria Bacillus, Lysinibacillus, Paenibacillus, and Sporosarcina [25]. Analysis of the air samples of SFH in Malaysia using 16S rRNA sequencing revealed 27 species of airborne bacteria, with Lysinibacillus spp., being the most common.…”

Phosphorous (V) Corrole Fluorophores for Nitrite Assessment in Environmental and Biological Samples

“…However, analyses of the last 5 years of publications on NO 2 − -sensor development have shown that less than 10% of all research is dedicated to sensors with optical transduction; this research is mainly dedicated to nanomaterial-based sensors, such as metal and metal-oxide nanoparticles [12,13], quantum dots [14], or liquid crystals [15]. Some applications of polymeric sensing materials doped with nitrite-selective ligands for optode development are also reported [16]. The accurate selection of the appropriate macromolecular ligands selectively binding to the target analyte has permitted the development of selective optodes for several inorganic anions, including nitrites [17][18][19][20].…”
