Real-time monitoring of the state of charge (SOC) in vanadium redox-flow batteries using UV–Vis spectroscopy in operando mode

Journal of Energy Storage, 2020
The state of charge (SOC) monitoring method of the vanadium redox flow battery (VRFB) is presented by UV–Vis spectroscopy of the charging-discharging of positive [V(IV)/V(V)] and negative [V(III)/V(II)] electrolytes in operando mode.

UV-Vis Spectroscopy

2013
In a UV-Vis (ultraviolet-visible light) spectroscopic measurement, light absorption as a function of wavelength provides information about electronic transitions occurring in the material. For semiconductors, UV-Vis spectroscopy offers a convenient method of estimating the optical band gap, since it probes electronic transitions between the valence ...

UV/Vis Spectroscopy

2009
The π π* transition of conjugated double bonds is above ≈200 nm with typical intensities of the order of log e ≈ 4. Its position can be estimated with the Woodward– Fieser rule.

UV–VIS absorption spectroscopy: Lambert-Beer reloaded

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2017
UV-VIS absorption spectroscopy is used in almost every spectroscopy laboratory for routine analysis or research. All spectroscopists rely on the Lambert-Beer Law but many of them are less aware of its limitations. This tutorial discusses typical problems in routine spectroscopy that come along with technical limitations or careless selection of ...

A turbidity compensation method for COD measurements by UV–vis spectroscopy

Optik (Stuttgart), 2019
In water quality detection by ultraviolet-visible (UV–vis) spectroscopy, the detection equipment faces diverse water bodies. It is easy to be interfered by turbidity caused by suspended solid particles (SSP), resulting in a nonlinear rise of the whole ...

UV–Vis Spectroscopy for Food Analysis

2021
Detection of food quality, authenticity, and adulteration is a great concern among consumers in the current market. Given the inherent complexity of food products, most instrumental techniques employed for quality and authenticity evaluation are time-consuming, expensive, and labor-intensive.
