Ternary Phase Diagram Modeling of Chiral Medetomidine Salts Using NRTL-SAC Model
Experimental determination of solubility and ternary phase diagram of chiral compound are of tedious and time consuming tasks, and in many cases, there is not enough experimental data for different enantiomeric compositions to access the experimental ternary phase diagram. Using thermodynamic models with predictive capability, having less dependency on experimental data, affords a great advanta...
متن کاملMean Activity Coefficients Measurements and Thermodynamic Modeling of the Ternary Mixed Electrolyte KCl + Lactose + Water System at T = 298.15 K
In this work, the mean activity coefficients of KCl in the KCl+lactose +water system were determined using the potentiometric method. The electromotive force measurements were carried out on the galvanic cell without liquid junction of the type: Ag|AgCl|KCl (m), lactose (wt.%), H2O (1−wt.) %|K-ISE, in various mixed solvent systems containing 0, 5,7.5, 10 and 12.5 % mass fractions of lactose. Th...
متن کاملIrregular Homogeneity Domains in Ternary Intermetallic Systems
Ternary intermetallic A–B–C systems sometimes have unexpected behaviors. The present paper examines situations in which there is a tendency to simultaneously form the compounds ABx, ACx and BCx with the same crystal structure. This causes irregular shapes of the phase homogeneity domains and, from a structural point of view, a complete reversal of site occupancies for the B atom when crossing t...
متن کاملRemoval of Methylene Blue, Malachite Green and Rhodamine B in a Ternary System by Pistachio Hull; Application of Wavelet Neural Network Modeling and Doehlert Design
Most of previous papers in the field of dye removal used one dye or dyes with nearly separate spectra that simplifies dyes concentration determination by Beer's law at different λmax. In many real situations, dyes with highly overlapped spectra exist and their concentrations can be determined by multivariate analysis methods. In this study, principal component-wavelet neural network (PC-WNN) wa...
متن کاملConstruction of S?-Selective Electrode and Thermodynamic Study of the Ternary Aqueous Mixed Electrolyte System (SrCl2, KG, H20) Using Potentiometric Method
In order to preparing strontium ion selective electrode 6-(4- nitropheny1)-2-pheny14, 4- dipropy1-3, 5-diaza-bicyclo [3, 1, 0] hex-2-ene (NPDBH) was used as an ionophore. This electrode responds to Sr (II)ion with a sensitivity of 28.2 ± 0.5 mV/decade over the range 1.0 x 10-6 to 1.0 Mat pH 3.0-10.0. Thelimit of detection was 2.4 x 10-7 M. The influences of membrane composition, the pH of the t...
