New “Magmolecular” Process for the Separation of Antimony(III) from Aqueous Solution

29-09-2014 | Ali Asghar Rooygar; Mohammad Hassan Mallah; Hossein Abolghasemi; Jaber Safdari, Journal of Chemical & Engineering Data, 2014

In this work, the separation potential of a new “magmolecular” process for ions of antimony(III) from wastewater was studied. The magmolecular process is a technique in which a high gradient magnetic field is applied to eliminate heavy metal from wastewater. In this process, specifically we have ...


Critical Evaluation of the Second Dissociation Constants for Aqueous Sulfuric Acid over a Wide Temperature Range

13-09-2013 | Hannu Sippola, Journal of Chemical & Engineering Data, 2013

The scope of this article is to study the ability of different equations for K2 and different sets of Pitzer parameters to model the thermodynamic properties of the H2SO4–H2O system over a wide temperature range. Three Pitzer parameters are found essential in modeling aqueous sulfuric acid, ...


Re-evaluation of the Mean Activity Coefficients of Strontium Chloride in Dilute Aqueous Solutions from (10 to 60) °C and at 25 °C up to the Saturated Solution Where the Molality Is 3.520 mol·kg–1

11-09-2013 | Jaakko I. Partanen, Journal of Chemical & Engineering Data, 2013

In the present study, two Hückel equations have been determined for the calculation of the mean activity coefficients of SrCl2 in pure aqueous solutions at 25 °C. The two-parameter equation with parameters B and b1 gives a good fit up to an ionic strength (= Im) of 2.0 mol·kg–1, and the ...


Phase Equilibrium of the Quaternary System Na2SO4–MgSO4–(NH4)2SO4–H2O at 0 °C

04-09-2013 | Jing Zhang; Hong-Fei Guo; Ji-Lin Cao; Rui-Jie Fan, Journal of Chemical & Engineering Data, 2013

The solubilities of the ternary system MgSO4–(NH4)2SO4–H2O and the quaternary system Na2SO4–MgSO4–(NH4)2SO4–H2O at 0 °C were measured, and the phase diagrams of these two systems were plotted. On the basis of the phase diagrams obtained, we analyzed each saturation point and crystalline region. ...


Determination and Correlation of Solubilities of (S)-Indoline-2-carboxylic Acid in Six Different Solvents from (283.15 to 358.15) K

04-09-2013 | Jin-Qiang Liu; Xin-Xiang Cao; Baoming Ji; Bangtun Zhao, Journal of Chemical & Engineering Data, 2013

The solubilities of (S)-indoline-2-carboxylilc acid (SIn2CA) in six pure solvents including water, methanol, ethanol, 1-propanol, 2-propanol, and 1-butanol were determined from (283.15 to 358.15) K at atmospheric pressure using the synthetic method. The solubility was determined by a laser ...


Study on the Phase Equilibrium of the Reciprocal Quaternary System Cd2+, K+//Cl–, SO42––H2O at 298 K

04-09-2013 | Yi Huang; Shi-jun Ni; Fang Zou; Shihua Sang, Journal of Chemical & Engineering Data, 2013

The solid–liquid equilibrium of reciprocal quaternary system Cd2+, K+//Cl–, SO42––H2O at 298 K was studied by an isothermal solution saturation method. Experimental results indicate that there are nine univariant curves F2E2, F4E4, E2E1, F3E1, E1E3, F5E3, F1E3, F6E4, and E4E2, four invariant ...
