Metal-ion recognition-competitive bulk liquid membrane transport of transition and post-transition metal cations using a thioether donor acyclic ionophore
The competitive bulk liquid membrane transport of Cr3+, Co2+, Cu2+, Zn2+, Cd2+, Ag+ and Pb2+ metal cations with a new synthetic sulfur donor acyclic ligand (pseudo-cyclic ionophore), i.e. 1-(2-[(2-hydroxy-3-phenoxypropyl)sulfanyl]ethylsulfanyl)-3...
Liquid–liquid extraction of aromatics from their mixtures with alkanes using 1-methyl 3-octylimidazolium thiocyanate ionic liquid
Experimental data for liquid–liquid equilibria (LLE) of ternary systems of {aromatic (ethyl benzene or
p-xylene) + alkane (hexane or heptane or octane) + ionic liquid} at T = 298.15 K and atmospheric pressure were studied. The ionic liquid 1...
Compressibility of Molecular Liquids and Liquid Mixtures
The linear pressure dependence of the bulk modulus of selected molecular liquids and liquid mixtures
has been investigated by using equations of state based on statistical-mechanical theory. The calculated
values of the bulk modulus...
Synthesis of trihalide ionic liquid as a new reagent for the bromination of aromatic compounds
Over the past decade, ionic liquids (ILs), salts with melting points near room temperature,
have been a subject of intense research as a customizable replacement for the
conventional organic solvents used in industry and academia...
Synthesis and crystal structure of a New N-(2,6-dichlorobenzoyl)-N\\',N\\"-bis(pyrrolidinyl)-phosphoric triamide as a carrier and competitive bulk liquid membrane transport of Co+2, Cd+2, Ag+, Pb+2, Ni+2 and Cu+2
as liquid membrane in these experiments. A good selectivity was observed for Pb+2 cation by this ligand in all membrane systems. Moreover, the selectivity of metal cations in DCM is higher than the other solvents. A non-linear relationship was found between...
New Regularities and an Equation of State for Liquids
Three regularities have been introduced for liqs. (T < TC and > C) based on av. potential energy. The exptl. data have been used to show the validity of the regularities. First, there exists near-linearity ...
Flow box test for viscosity of soil in plastic and viscous liquid states
Unified control of a buck converter for wide load range applications
Response surface methodology for modelling and determination of catechin in Pistachio green hull using surfactant-based dispersive liquid–liquid microextraction followed by UV–Vis spectrophotometry
A rapid and simple approach for the preconcentration and determination of catechin from pistachio green hull samples has been proposed by surfactant-assisted dispersive liquid–liquid microextraction followed by UV–Vis spectrophotometry (SADLLME...
