RISPreconcentration of thallium (III) by single drop micro extraction and its determination by electrothermal atomic absorption spectrometry in real samples and speciation of thallium (I) and (III)
Abstract
Single drop micro extraction (SDME) in combination with electrothermal atomic absorption
spectrometry has been used to preconcentrate and determine thallium (III) ions followed by
speciation ...
Studies on the macrocycle mediated transport in a bulk liquid membrane system of transition metal cations
A series of competitive metal ion transport experiments have been performed. Each involved transport from an aqueous source phase across an organic membrane phase into an aqueous receiving phase. The source phase consisted ...
Separation study of some heavy metal cations through a bulk liquid membrane containing 1,13-bis(8-quinolyl)-1,4,7,10,13-pentaoxatridecane
Competitive permeation of seven metal cations from an aqueous source phase containing equimolar concentrations of Co2+, Fe3+, Cd2+, Cu2+, Zn2+, Ag+ and Pb2+ metal ions at pH 5 into an aqueous receiving phase at pH 3 through ...
A new supramolecular based liquid solid microextraction method for preconcentration and determination of trace bismuth in human blood serum and hair samples by electrothermal atomic absorption spectrometry
A simple and reliable supramoleculeaggregated liquid solid microextraction method is described for preconcentration and determination of trace amounts of bismuth in water as well as human blood
serum and hair samples. ...
Second-Order Advantage From Micelle Concentration Gradual Change–Visible Spectra Data
Second-order calibration is used for second-order data. Such data is produced by instruments that give a matrix of responses for a
single measured standard or unknown sample. This allows for determination of analyte ...
Quantitative Structure-Retention Relationships Study of Phenols Using Neural Network and Classic Multivariate Analysis
A quantitavi structure- relationship (QSRR) study has been carried out on 50 diverse phenols in gas chromatography (GC) in a dual-capillaryc olumn systemm adeo f DB-5 (SE-54b ondedp hase)a ndD B-17 (OV-I 7 bondedp hase)f ...
