recommendations! Published in 2021 at "Analytica chimica acta"

DOI: 10.1016/j.aca.2020.12.061

Abstract: A major challenge hindering the application of techniques like UV/Vis spectrophotometry in determining concentration is spectral interference from contaminants. Since molar absorptivities vary significantly, even minuscule amounts of specific contaminants may cause relatively large errors… read more here.
