Abstract
Ultrasonic investigation has become very popular tool nowadays. It is based on Nondestructive Testing^1-2 (NDT). Ultrasonic study has proved to be beneficial in understanding the chemical behavior of the particular system. Present study of pure Aloe Vera barbadensis Miller Juice (AV Juice) and some common solvents³ such as Water, Ethanol (EtOH), n-Butanol (n-BuOH) and Acetic acid is important due to its wide range of application in medicinal and industrial field. Aloe Vera has chemically weak acidic nature. We have measured Density(ρ), Viscosity(η), Surface tension(γ) and Ultrasonic velocity (U) of Aloe Vera juice (AV Juice) first time than calculated Adiabatic compressibility (βa),Acoustic impedance (Z), Intermolecular free length (Lf), Viscous relaxation time (Ï„) and Gibb’s free energy (∆G). We have reported ultrasonic velocity of Acetic acid, Ethanol, n-Butanol and Aloe vera juice (AV juice) with compare to distilled water at 296K temperature and 2MHz frequency.
