Rapid electrochemical sensor for uranium(vi) assessment in aqueous media

Abstract

A new Schiff base was synthesized and applied as ionophore to construct potentiometric sensor for uranium(vi) determination.

Threonine Phosphorylation of an Electrochemical Peptide-Based Sensor to Achieve Improved Uranyl Ion Binding Affinity

“…Table 1 shows the key analytical properties of the U-pT-12 sensor and several previously reported U(VI) sensors and detection methods [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. The LOD of the current sensor compares well with several other U(VI) sensors, including colorimetric, SERS, and electrochemical sensors [ 11 , 13 , 14 , 15 ].…”

The LOD of the current sensor compares well with several other U(VI) sensors, including colorimetric, SERS, and electrochemical sensors [ 11 , 13 , 14 , 15 ]. Although there are sensors with significantly lower LODs [ 10 , 12 ], these sensors require custom designed and synthesized U(VI)-specific ligand and/or nanomaterials.…”

“…These techniques include inductively coupled plasma mass spectrometry [ 7 , 8 ], UV spectrophotometry [ 9 , 10 , 11 ], fluorescence spectroscopy [ 12 ], and surface enhanced Raman spectroscopy (SERS) [ 13 , 14 ]. Various electrochemical U(VI) detection approaches have also been reported recently [ 15 , 16 , 17 , 18 ]. Most electrochemical detection methods involve the use of modified electrodes.…”
