The polarographic determination of stability constants of metal complexes of Thallium(I) with Ornithine monohydrogen chloride under varying temperatures 300K and 313K in aqueous media have shown the formation of 1:1, 1:2 and 1:3 complexes. The values of overall stability constants of complexes have been calculated by DeFord and Hume’s method which is further verified by Mihailov’s method. The r...

The polarographic determination of stability constants of metal complexes of In(III) with 2,2 ́ oxydiacetic acid under varying temperatures, at 300K and 310K and in various aqueous-nonaqueous media, have shown the formation of 1:1 and 1:2 complexes. The values of overall stability constants of complexes have been calculated by DeFord and Hume's method which is further verified by Mihailov's meth...

A recent technique involving the use of paper electrophoresis is described for the study of equilibria in binary complex systems in solution. The stability constants of the ML and ML2 complex species of some metal ions, namely beryllium(II) and cobalt(II), with hydroxyproline were determined in 0.1 mol L perchloric acid and a temperature of 35 °C. The logarithm stability constants of the ML and...

The thermal stability of Newcastle disease virus has been characterized in terms of the rate constants for inactivation of hemagglutinating activity (HA), neuraminidase activity (NA), and infectivity. Inactivation of HA results in the concomitant loss of NA. Infectivity, however, is much more thermolabile. Disintegration of the virus particle is not responsible for the identical rate constants ...

The application of convolution potential voh.ammetry to questions of metal complexation is described. Theoretical relations are derived to show that the stability constants may be directly related to the shift in the peak potential of the semiderivative wave, provided the complexes are labile. Equations are also given for inert and quasilabile complexes. Stability constants for the PbCI, and Cd...

Dissolved organic matter (DOM) has been implicated as an important complexing agent for Hg that can affect its mobility and bioavailability in aquatic ecosystems. However, binding constants for natural Hg-DOM complexes are not well known. We employed a competitive ligand approach to estimate conditional stability constants for Hg complexes with DOM isolates collected from Florida Everglades sur...

Determination of the stability constants of dissolved iron(III) glycine system in water solution (I = 0.6 mol L in NaClO4, pH = 7.3 at 25±1 oC) using differential pulse cathodic voltammetry (DPCV) and cyclic voltammetry (CV) was performed out on a static mercury drop electrode (SMDE). By choosing voltammetry as analytical tool, measurements with lower iron(III) concentrations (10 mol L), at the...

the dependence on ionic strength of protonation of l-aspartic acid and its complexation withdioxouranium(vi) is reported in sodium perchlorate solution as a background salt. the measurementshave been performed at 25 ± 0.1 °c and various ionic strengths in the range 0.1 to 1.0 mol dm-3, using acombination of potentiometric and spectrophotometric techniques. the overall analysis of the present an...

This paper provides a discrete Poincaré inequality in n space dimensions on a simplex K with explicit constants. This inequality bounds the norm of the piecewise derivative of functions with integral mean zero on K and all integrals of jumps zero along all interior sides by its Lebesgue normbyC (n)diam(K ). The explicit constantC (n) depends only on the dimension n = 2,3 in case of an adaptive ...
