چکیده

The rational design of a mercury(II) ligand consisting in a 1-(4'-oxyphenyl)-4(1'-pyrenyl)-2,3-diaza-1,3-butadiene receptor unit, optimizes the sensitivity and reliability of a SPR sensor by the formation of a well packed SAM over the gold surface. SPR analysis allows detecting mercury(II) concentrations in aqueous systems in the picomolar range, meliorating on three orders of magnitude the EU mercury(II) detection limit in drinkable water.

DETERMINATION OF ULTRA-TRACE AMOUNTS OF COBALT BY ADSORPTIVE DIFFERENTIAL PULSE VOLTAMMETRY USING ACDA (2-AMINOCYCLOPENTENE- 1-DITHIOCARBOXYLIC ACID)

The present work describes a selective, rapid and sensitive method for the determination of cobalt using the adsorptive differential pulse voltammetry technique. The method is based on the accumulation of Co(II) complex with 2-aminocyclopentene-1-dithiocarboxylic acid on a hanging mercury drop electrode, followed by measurement of the current of the adsorbed complex. The effects of experimental...

A glance into the bulk of solvent polymeric pH membranes*

The pH-sensitive chromoionophores brought the dream of the ion-selective membrane scientist close to realization. With the help of these molecules, one can build pH-sensitive, ion-selective electrodes and look into the bulk of solvent polymeric membranes during potentiometric measurements (spectropotentiometry) and image concentration profiles in situ with high spatial and temporal resolution. ...

Simultaneous detection of mercury(II) and silver(I) ions with picomolar sensitivity.

We develop a new method for the simultaneous detection of Hg(2+) and Ag(+) by integrating bifunctional strand displacement amplification and multiplexed short linear quencher-fluorophore probes. This method exhibits excellent specificity and high picomolar sensitivity, which is improved by up to 4 orders of magnitude compared to the current approaches for metal ion assay.

Design and Evaluation of a Mercury (II) Optode Based on Immobilization of 5, 6 Di methyl -1- (4 methyl benzyl) -2- para tolyl-1H-benzimidazole (DMBPTBI) on a Triacetylcellulose Membrane and Determination in Various Samples

The characterization of an optical sensor membrane is described for the determination of Hg2+ ions based on the immobilization of 5, 6 Di methyl -1- ( 4 methyl benzyl) -2- para tolyl-1H-benzimidazole (DMBPTBI) on a triacetylcellulose membrane. The membrane responds to mercury ions by changing color reversibly from orange to red in universal buffer solution at pH 2. Under optimum conditions, the...

Ion Selective Carbon Paste Electrode For The Determination Of Flavoxate Muscle Relaxant Drug In Pharmaceutical Formulation

Abstract The utility of carbon paste electrode for the determination of flavoxate HCl modified with flavoxate-tetraphenylborate (FLX-TPB) and flavoxate-phosphotungestic acid (FLX-PTA) ion-pairs in batch mode is demonstrated. The electrodes revealed a Nernstian response over a wide concentration ranges 1.39×10-5-1x10-2 mol L-1 and1×10-5-1x10-2 mol L-1 using FLX-TPB and FLX-PTA, respectively. The...
