Abstract
An analytical approach of quantifying various chemical species, using Raman spectrometry in conjunction with equilibrium modeling, has been tested on aqueous solutions containing Nd, Cu, and dipicolinic acid. Equilibrium modeling was used to select optimum conditions in simple solutions for the determination of concentration-Raman intensity relationships. These relationships were then used to interpret spectra from more complex solutions and to make comparisons with equilibrium modeling results from the same systems. Peak heights were determined through curve fitting of the spectra using nonlinear regression and were normalized using ClO4(-1) as an internal standard.
