Liquid-Liquid Equilibria of the Phosphoric Acid, Ester and Water Ternary System

Abstract

This paper presents an experimental methodology used for the determination of liquid-liquid equilibrium (LLE) data of the ternary system (phosphoric acid, ester and water). This experimental methodology represents the determination of phosphoric acid linked with different aquatic systems. In this study, an ester was selected as an organic solvent for the recovery of phosphoric acid from waste water. The binodal curve and the tie lines have been prominent. The ternary system (water + phosphoric acid + ester) was studied at three temperatures i.e. 25, 35 and 45 °C (298, 313 and 323 K). The results indicate that the extraction of phosphoric acid by a solvent is possible in aquatic systems. The results are discussed.

Evaluation of Total Concentrations and Extractable Fractionations of Cd, Co and Ni in Soils from Dumpsites across Rivers State, Nigeria

“…The interaction of trace elements forms complexes on a mineral surface (Rieuwerts et al, 1998). The results from the correlation analysis suggest that trace elements interact with each other and could be relatively mobile along the soil profiles (Jena et al;2013;Kedir et al;2017).…”

Comparative Study of Liquid–Liquid Equilibria for Aqueous Mixtures of Phosphoric Acid with Two Structurally Similar Carbonyl Compounds: Measurement and Correlation

“…Until now, numerous studies have been performed on the liquid–liquid equilibrium (LLE) behavior of the aqueous systems containing PA and organic solvents. − However, advance investigations are still crucial and required for a variety of industrial purposes. As far as the authors are aware, the chemicals with different functional groups such as aliphatic or aryl alcohols, carbonyls (ketone and ester), and hydrocarbons have mainly been examined as an extractant for the acid recovery from water.…”
