Real-Time Quantification of Nickel, Cobalt, and Manganese Concentration Using Ultraviolet-Visible Spectroscopy-A Feasibility Study

In the present study, the feasibility of the real-time quantification of nickel, cobalt, manganese, and lithium concentration is investigated using Ultraviolet-Visible spectroscopy as a replacement for the conventional method to measure the concentrations of these elements in battery and other applicable industries. Ultraviolet-Visible spectroscopy is one of the most effective, flexible, inexpensive, and simplest analytical techniques to measure species concentration. This technique has a wide range of applications such as wastewater treatment to colloidal nanoparticle characterization. To carry out this study, samples with different concentrations of selected elements are prepared and analyzed using an Ultraviolet-Visible spectrometer. Mathematical relationships are defined between concentration and absorbance and calculated concentrations are compared with ICP-OES results. The effect of elements concentration and path length on absorbance is analyzed to verify the feasibility of the method in the industry.
