Title: Quantification of dissolved metals in high-pressure CO2-water solutions by underwater laser-induced breakdown spectroscopy

Abstract

This paper reports quantitative measurements of dissolved metals concentrations in CO2-water solutions by using underwater laser-induced breakdown spectroscopy (underwater LIBS). The CO2 pressure was varied over the range from 10 to 400 bar. The concentrations of naturally occurring elements of environmental significance such as Mg, Ca, Sr, Ba and Mn were determined by spectral analysis. Parametric dependence for improvement of underwater LIBS sensitivity was carried out. The results successfully demonstrate that low-ppm range concentrations of Mg2+, Ca2+, Sr2+, Ba2+ and Mn2+ can be accurately measured in CO2-laden water at varied pressure conditions by using underwater LIBS.
