Volumetric and acoustic characteristics of a temperature-dependent aqueous solution of trisodium EDTA with EG, DEG and TEG
Abstract
The apparent molar volume(Vϕ) and apparent molar isentropic compressibility (Kϕ,s) of ethylene glycol (EG), diethylene glycol (DEG) and triethylene glycol (TEG) in trisodium ethylenediaminetetraacetic acid solution (aqueous) have been estimated based on measured experiments values for both the density (ρ) and sound speed (s) at (288.15, 298.15, 308.15 and 318.15) K and 0.01 MPa as well. From the foundation in infinite dilution limiting apparent molar volumes (Vϕ∘) and isentropic compressibility(Kϕ,s∘) its transfer properties (ΔVϕ∘, ΔKϕ,s∘), expansibility coefficients(∂Eϕ∘/∂T)P, expansion coefficient (α) and interactions coefficients (VAB,KAB,VABB,KABB) the various interactions among glycols and EDTA in aqueous solution were investigated and addressed. Fourier transform infrared spectroscopy study had also been carried in binary solution.
