A Fluorescence-Based Sensor for Ammonium and Nitrate

On the role of graphene oxide in bifunctional Ni/MOF/rGO composites in electrochemical nitrate detection and oxygen evolution reaction

“…Since nitrates pose a significant risk to the economy, human health, and the environment, it is crucial to check them on-site and often. Among the analytical methods used to find nitrate are colorimetric detection, 17 spectrophotometry, [18][19][20][21] spectrofluorimetry, 22 ion chromatography, [23][24][25][26][27][28] capillary electrophoresis, 29 polarography, 30 Raman spectroscopy, 31 chemiluminescence methods, 26,28 and field-effect transistor based methods. 32 However, the majority of these methods need laborious sampling processing, costly equipment, plenty of space, and qualified personnel to run.…”

Novel selective optode membrane for terbium ion based on fluorescence quenching of the 2-(5-(dimethylamino) naphthalen-1-ylsulfonyl)-N-henylhydrazinecarbothioamid

“…This is mainly due to its inherent sensitivity, its almost complete inertness to turbidity and its flexibility with respect to geometric arrangements [3][4][5][6]. There is an increasing current interest in the development of fluorescent sensors for metal ions such as Li + [7], Na + [8,9], Ag + [10], Hg 2+ [11], Co 2+ [12], Cu 2+ [13], Ni 2+ [14], Al 3+ [15], and Zn 2+ [16] as well as a number of anionic species [17][18][19].…”

Electrodeposition of Copper Thin Films on Screen Printed Carbon Electrodes towards Electrochemical Sensing of Nitrate

“…12 For the detection of NO 3 − , different analytical methods have been reported, which includes, colorimetric detection after reduction to NO 2 − , spectrophotometry, Raman spectroscopy, chemiluminescence, chemiresistive and field-effect transistors. [13][14][15][16][17] However, the majority of these techniques need labour-intensive sample procedures, cutting-edge equipment, a large working area, and qualified personnel to operate. Complicated working procedures, expensive analysis, and time consumption are the notable downsides.…”
