In the present study, the feasibility of the real-time quantification of nickel, cobalt, manganese, and lithium concentration was 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. The technique has a wide range of applications such as wastewater treatment to colloidal nanoparticle characterization. To carry out the study, samples with different concentrations of individual elements and composites were prepared and analyzed using an Ultraviolet-Visible spectrometer. Mathematical relationships were defined between concentration and absorbance, and calculated concentrations were compared with ICP-OES results. The effect of various parameters such as elements concentration, path length, number of elements in the solution, density, and pH on absorbance was analyzed to verify the feasibility of the method in the industry.
