Spark Discharge–Facilitated LIBS Coupled with Electrodeposition for Highly Sensitive Detection of Chromium Within Aqueous Matrices

Photonics
In this study, electrodeposition (ED) combined with a spark discharge-facilitated laser-induced breakdown spectroscopy—referred to as SD-LIBS—was employed for highly sensitive detection of trace chromium (Cr) in aqueous solutions. First, trace Cr ions in
