Dr. T. Charan Singh*

ABSTRACT

Molecular complexes of Paraquat (PQ) with a para Chloro phenyl hydrazones in SDS micellar medium has been studied spectrophotometrically. The entire complexes exhibit one charge transfer band each in the region where neither of the components has any absorption. The formation constants of the complexes have been determined by using Fronasiero and Grieser mothod. The extinction coefficients (ε) and apparent formation constant of CT complexes have been determined by Rose-Drago method. The positions of the CT-Bands in SDS are closed to those of the CT-Bands in methonol.

Keywords: Paraquat, Sodium dodecyl Sulfate (Micellar Medium) and para Chloro phenyl hydrazones.
