Benzo (a) pyrene belongs to a class of Polycyclic aromatic hydrocarbon (PAH) that serves as micro pollutants in the environment. It has been reported as probable carcinogen in humans. PAHs has low water solubility. Solubility of PAHs can be increased by using surfactants to reduce surface tension and interfacial tension. The solubilization of Benzo (a) pyrene solubilizate into the micellar core of certain surfactants have been studied and analyzed with the help of Fluorescence spectroscopy. The increase in fluorescence intensity on addition of surfactant can be attributed to the increase in quantum efficiency suggests that the surfactants have solubilized the suspended molecule. The solubilization phenomenon was also confirmed by absorption spectral studies and light scattering measurements. Theoretical parameters were also determined; the calculated results are in fair agreement with the experimental results. This proves the validity of work done.
