In this paper, the formation of ordered structures at pentacene/Ag(111) interface is investigated. Pentacene molecules are thermally evaporated and deposited onto a Ag(111) substrate held room temperature. The studied with combination x-ray photoelectron spectroscopy (XPS), low energy electron diffraction (LEED), high resolution loss (HREELS), scanning tunneling microscopy (STM). To begin with, pentacene form loosely bound, disordered contact layer in which oriented parallel to surface....
Abstract The extraction of copper(D) from concentrated chloride ion solutions by various pyridinecarboxylic acid esters is investigated. It shown that the efficiency strongly dependent on water activity (aw) and total concentration (σ) ionic or molecular species dissolved in aqueous phase. For decyl nicotinate, isonicotinate, picolinate ACORGA CLX-50 (all denoted EXT) toluene, distribution copper(II) can be satisfactorily represented formation CuCl2(EXT)2 organic phase condition taking into...
In this paper we present a detailed analysis of the molecular mechanisms perylene and PTCDA bonding to two close-packed noble metal surfaces, Ag(111) Au(111), with aim elucidating relation between interface structure. Our is based on combination high-resolution electron energy-loss spectroscopy first-principles quantum chemical calculations (density functional theory) orbitals vibrations. Experimentally, key observation activation certain totally symmetric modes by symmetry breaking at...
ABSTRACT The diphasic acldo-basic properties of three dialkylorgeno-phosphorus odds, namely di-2-ethylhexylphosphoric acid (DEHPA),2-ethyl-hexylphosphonlc acid, mono-2-ethylhexyl ester marketed as PC 88A and di(2,4,4-trimethylpenty1) phosphinic CVANEX 272, their ability to form aggregates have been investigated by acidimetry in presence 1 mol.dm-3 NaC104 computer simulation, A mathematical model, which is equivalent the reality, proposed.
ABSTRACT The extraction of Rh(III) from chloride solutions with 2 different 7-substituted 8-hydroxyquinoline (R-HQ) reagents was studied. found to be extracted, a limited degree, via an ion-pair involving the anionic hexachloro species Rh(III), RhCl6 3−, and protonated extractant. Through computer simulation equilibria for one extractant, TN 1911, constant log Kex= 5.8 determined. effect age, contact time, [HCI], [CI−], [H+], [SO4 2] on R-HQ is reported.
ABSTRACT The solvent extraction of indium(III)from mixed 0.5 to 1 mol.L hydrochloric acid + 2 4 mol.L−1 sulphuric solutions simulating flue dust leaching was investigated. In addition In(III) typically present at about g.L-', the contain As(III), Cd(II), Cu(II) Fe(IH) and Zn(II), with concentrations ranging between 3 25 g.L*1. After preliminary investigation, bis(2,4,4-trimethylpentyl)phosphinodithioic Cyanex 301® selected as extractant. Indium(III) is efficiently extracted by in range...
ABSTRACT The solvent extraction of antimony (in), bismuth (111), lead (II) and tin (IV) from aqueous hydrochloric acid solutions by bis(2,4,4-trimethylpentyl) phosphinodithioic (Cyanex 301® denoted HL) in kerosene + 10 % v/v n-decanol was investigated. Lead (II), (IV), (III) are efficiently extracted Cyanex up to about 5, 6, 9 11 mol.L1− HCl, respectively. corresponding species were identified as PbL2, SnCl2L2, BiL3 SMvj. However, it observed that Sn can be moderately the phase mere mixture...

ABSTRACT The distribution equilibria of In(III) and Cd(II) between aqueous HCl solutions kerosene containing Cyanex 301 (bis(2,4,4-trimethylpentyl) dithiophosphinic acid denoted hereafter HL) 10 % (V/V) n-decanol are investigated. extracted as InL3 CdL2, respectively a physico-chemical model is proposed for modelling the data. In final part paper, this, used to discuss optimal conditions separating indium cadmium, previously co-extracted with 301, by stripping in media.
