EFFECT OF GLUCOSE ON PHYSICO-CHEMICAL PROPERTIES OF SOME SURFACTANT SOLUTIONS
Abstract: Physico-chemical and thermodynamic studies of some aqueous surfactant solutions were carried out by employing conductance and dye solubilization (UV-Vis absorption spectroscopy) techniques. From the above measurements, critical micelle concentration (CMC) and thermodynamic properties of micellization (ΔGomic , ΔHomic and ΔSomic) have been obtained for an anionic [Sodium dodecyl sulphate (SDS)],a cationic [hexadecyl trimethyl ammonium bromide, (HTAB)] and non ionic (Tween-20) surfactant solutions. Effect of mixing cosolute on CMC and thermodynamics …

Model for Prediction of Pneumatic Proportional Integral Controller Transfer Function for Step Input Process Response
Abstract: Mathematical model was developed to monitor, predict and simulate the pneumatic proportional integral controller transfer function for step input process response. The model developed was based on the geometric arrangement as well as the distance of the flapper from the nozzle was considered to be small, where the capacitance C is constant and R is the resistance of the integral restrictor. The characteristics of the process was monitored, predicted and …

Modeling of CSTR Reactor for Sodium Benzoate Production
Abstract: The mathematical model was developed for Continuous Stirred-Tank Reactor (CSTR) for the production of sodium benzoate from the reaction of sodium hydroxide and benzoic acid. The performance equation for the operation of CSTR was developed for the analysis of the reactor’s functional dimensions and parameters. The analysis of the reactor’s functional parameters was performed at molar ratio of benzoic acid to sodium hydroxide of 1.5 to 3.0 at intervals of …

Kinetics of oxidation of Isonicotinic Acid Hydrazide by Iron (III)-2,2ı-Bipyridyl complex-Micellar effect of Sodium DoDecyl Sulphate
Abstract: The kinetics of oxidation of Isonicotinic Acid Hydrazide (INH) using Iron (III) -2,2ı-Bipyridyl complex was studied spectrophotometrically in acidic medium. The stoichiometry of the reaction between INH and Iron (III) - 2,2ı-Bipyridyl complex was found to be 4:1. The rate of the reaction is enhanced by increasing [acid]. The reaction obeys first order kinetics with respect to iron (III) and 2, 2’Bipyridyl.The rate of the reaction is markedly accelerated in …
