Stability constant (log ) and thermodynamic parameters of Cd complexes with sulfonamide and cephapirin were determined by Polarographic technique at pH = 7.30 ± 0.01 and μ = 1.0 M KNO3 at 250°C. The sulfonamides were sulfadiazine, sulfisoxazole, sulfamethaxazole, sulfamethazine, sulfathiazole, sulfacetamide and sulfanilamide used as primary ligands and cephapirin as secondary ligand. Cd formed ...

The solubility of KNO3 in the mixed solvent (water 85%+methanol 15%) were determined by using solvent evaporating method at different temperatures (25, 30, 40, 50, 60 ;C). In addition the equilibrium constant of ion pair formation, KIP, for K+NO3 – ion-pair on the basis of Fuoss contact ion pair model was calculated. Upon choosing the extended Debye-Hückel model for estimating the mean activity...

The aim of this contribution is a survey of different nucleation and growth kinetics terms effects on modeling results of KNO3 Continuous Mixed Suspension Mixed Product Removal (CMSMPR) crystallizer. By studying the four different states in modeling, results show that, although these terms for similar crystallization system and operating conditions are similar, there is very different dynamic b...

Mixed ligand complexes of some transition metals[ Cu(II),Ni(II), Co(II) and Zn(II)] have been investigated Potentiometrically with Pyridine-2,6-dicarboxylic acid(PDA) and 2-hydroxy benzalidine-anthranilic acid (HBAA) in aqueous solution at 298.15 K and 313.15 K. The ionic strength of 0.1 mol dm-3 was kept constant using KNO3. The stability constants of these 1:1:1 ternary complex have been eval...

The components of the proton motive force (delta p), namely the membrane potential and the transmembrane pH gradient, were measured in washed cells of Rhizobium japonicum CC705 grown in cultures (5% O2-95% N2) in the presence of 10 mM KNO3 and in bacteroids from Glycine max. The delta p and its components remained reasonably constant in cells as well as in bacteroids at various stages of growth...

This paper describes an experimental test of the uni®ed theory of thermal shock. A borosilicate glass (78.1%SiO2± 13.3%B2O3±4.7%Na2O±3.4%Al2O3) subjected to ion-exchange in molten KNO3, was used. The theory predicts the critical temperature di€erence for fracture initiation by thermal shock; however, it overestimates the number of cracks which propagate simultaneously. Despite that fact, taken ...

8 ABSTRACT: A pentamethylcyclopentadienyl (Cp*) iridium water9 oxidation precatalyst was modified to include a silatrane functional group 10 for covalent attachment to metal oxide semiconductor surfaces. The 11 heterogenized catalyst was found to perform electrochemically driven 12 water oxidation at an overpotential of 462 mV with a turnover number of 13 304 and turnover frequency of 0.035 s−1...

The work described here comprises the determination of Fe(III) by ion selective potentiometry using a coated-wire ion-selective electrode (CWISE) based on iron–cyclam complex. Linear Nernstian response for this electrode was obtained over the total Fe(III) concentration range of 1× 10−2 to 1× 10−6 M in 0.05 M HNO3, H2SO4, HClO4, HCl, KNO3 and KCl media, with a slope of 60± 5 mV per decade chang...
