Acoustical Investigation on Physico Chemical Behaviour of the Binary Liquid Mixtures of Inorganic Salts and Aqueous Polymer Solutions

Study on the properties of polymer solutions have been extensively used for under standing solute-solvent and solute-solute interactions. Polyvinyl Pyrrolidone (PVP), an amorphous water soluble synthetic polymer, is used by a wide variety of industries, such as medicine, cosmetics, textile, adhesives, because of its interesting properties such as low cytotoxicity. PVP are used in DNA and RNA extractions from plants. Ammonium per sulphateis a strong oxidizing agent and radical initiator. It has also been utilized to study protein - protein interactions via photo initiated cross linking chemistry. The present thesis deals with ultrasonic and thermo dynamical properties of aqueous mixtures of zinc sulphate and manganese sulphate with polyvinyl pyrrolidone (PVP) at 303 K, 308 K and 313 K. Physico-chemical study also has been made in the present thesis in the aqueous inorganic salt mixtures by with the help of acoustical excess parameters and theoretical velocities at 303 K. The present dissertation encompasses VI chapters. Chapter-I deals with the introductory aspects of ultrasound investigation of molecular interaction in the liquid mixtures. A relevant review of literature to the present work has also been presented.
