The Spectrophotometric Multicomponent Analysis of a Ternary Mixture of Paracetamol, Aspirin, and Caffeine by the Double Divisor-Ratio Spectra Derivative Method

Figure 5

Standard addition plot for the derivative of double divisor-ratio spectra for a mixture of ASP (50 μmol L−1), CAF (20 μmol L−1), and PAR (20 μmol L−1) after standard addition of three components in the same mole ratios in the concentration range of 10–60 μmol L−1. The initial solution contains a ternary mixture of ASP (50 μmol L−1), CAF (20 μmol L−1), and PAR (20 μmol L−1).
