Abstract

Fluorescence intensities of propranolol and atenolol in binary solvent mixtures at various temperatures are measured and mathematical models are proposed to represent the fluorescence intensity data. The results showed that the proposed models are able to correlate/predict the data with reasonable error. The fluorescence intensity of pyridoxal HCl in binary solvents at 25 °C is also determined and represented by the proposed model as an additional test probe.
