Paper Title:

Calculation of Surface Tension and Viscosity of Liquid Transition Metals

Abstract:  The results of calculations of structure and some surface properties such as, isothermal compressibility, surface tension and viscosity for liquid 3d transition metals, Ti, Ni and V, near melting temperatures are presented. We used the parameters of the Wills-Harrison (WH) approximation in conjunction with the Bretonnet-Silbert (BS) local model pseudopotential, which is suggested separate description of the s- and d—electron states are calculated using Dubinin procedure [1]. Isothermal compressibility and surface tension  properties of Ti, Ni and V are calculated using extended Mayer’s empirical formula in terms of hard sphere diameter and packing fraction which calculated using Waseca’s formula [2]. We have obtained in very good agreement near melting point with available experimental data.

Keywords:
  transition metal, scaled particle theory, surface tension, viscosity.

Paper Title:

Determination of Uranium (VI) in Underground Water and Rock Samples by Adsorptive Cathodic Stripping Voltammetry

Abstract: Uranium (VI) forms a complex with potassium hydrogen phthalate. This complex is adsorbed onto a hanging mercury drop electrode (HMDE) and uranium is determined by differential pulse cathodic stripping voltammetry (DPCSV). This method is applied for the determination of U (VI) in 10 rock samples and 15 underground water samples. The reduction current of adsorbed complex of uranium (VI) was measured by differential pulse cathodic stripping voltammetry (DPCSV), preceded by a period of accumulation onto the electrode surface. Concentration of U(VI) found were ranged from: nil  ــ 3.34µgL-1in ground water samples and 0.167 – 3.637 mgkg-1 in rock samples. The statistical parameters (standard deviation, correlation coefficients, for estimation and confidence interval for standard deviations) are made by linear regression method. The values reveal the accuracy and reliability of the proposed method for monitoring of U(VI) in underground water and rock samples.

Keywords:
Differential pulse cathodic adsorptive stripping voltammetry, Uranium, Uranium (VI), rocks, underground ground water samples.
