Recently we introduced a nonlinear partial differential equation (nPDE) of the third order for the first time. This new model equation allows the extension of the Debye-Hückel Theory (DHT) considering time dependence explicitly. This also leads to a new formulation in the meaning of the nonlinear Poisson-Boltzmann Equation (nPBE) and therefore we call it the modified PoissonBoltzmann Equation (...

In this work, the results concerning to the mean activity coefficient measurements for NaCl in the (glycerol + water) system using the potentiometric method are reported. The potentiometric measurements were performed on the galvanic cells without liquid junction of the type: Ag|AgCl|NaCl (m), glycerol (wt%), H2O (1 - wt)%|Na-ISE, in various mixed solvent systems containing 0, 5, 10,...

Abstract Municipal wastewater is an interesting source of phosphorus and several processes for the recovery from this have been described. These yield magnesium ammonium phosphate (MAP), a valuable fertilizer. In these processes, pH shifts addition chemicals are used to influence species distribution in solution such as finally obtain desired product prevent co-precipitation salts heavy metal i...

in this research complexation of dioxovanadium(v) with nitrilotriacetic acid (nta) at differentionic strengths (0.1 to 1.0 mol dm-3) of sodium perchlorate as supporting electrolyte and ph rangeof 1.00-2.50 at 25 °c has been investigated by a combination of potentiometric and uvspectrophotometric measurements. stability constants of two species, v0211l- and vo2h2l havebeen calculated. ionic stre...

Near-critical thermodynamics in the hard-sphere (1, 1) electrolyte is well described, at a classical level, by Debye-Hückel (DH) theory with s1, 2d ion pairing and dipolar-pair-ionic-fluid coupling. But DH-based theories do not address density fluctuations. Here density correlations are obtained by functional differentiation of DH theory generalized to nonuniform densities of various species. T...

We study the free energy of a heavy quark-antiquark pair in a thermal medium. We constuct a simple ansatz for the free energy for two quark flavors motivated by the Debye-Hückel theory of screening. PACS. 11.15.Ha, 12.38.Mh, 25.75.Nq

in this work, the results concerning to the mean activity coefficient measurements for nacl in the (glycerol + water) system using the potentiometric method are reported. the potentiometric measurements were performed on the galvanic cells without liquid junction of the type: ag|agcl|nacl (m), glycerol (wt%), h2o (1 - wt)%|na-ise, in various mixed solvent systems containing 0, 5, 10, 20 and 30 ...
