Intermolecular Interactions Studies of ZnO-Tryptophan Suspension

The physicochemical properties (PCPs) have been studied to demonstrate the intermolecular interactions of ZnO nanoparticles (NPs) suspension. Tryptophan (Tryp) was dissolved in water and used as dilute solution to study the dispersion of ZnO NPs in different concentrations (25 to 150 uM) with 25 step. Density p, apparent molar volume V®, refractive index (RI) nD and speed of light c have been reported. Man Singh equations were used to calculate the viscosity tj, surface tension y and friccohesity a, activation energy Ay*2 was calculated using Arrhenius equation on the basis of pendant drop number (PDN) and viscous flow time (VFT) which counted by Borosil ManSingh Survismeter (BMS) instrument for solutions at room temperature. The physicochemical properties revealed the effect of ZnO NPs concentration on intermolecular interactions in dispersion systems. The results depicted the strong role of Tryptophan on ZnO NPs dispersion process in the term of solute-solvent and solute-solute interactions and free chemical reaction suspension.
