Potentiometric detection of mercury(II) ions using a carbon paste electrode modified with substituted thiourea-functionalized highly ordered nanoporous silica.
A potentiometric sensor is reported for the mercury(II) detection, which uses substituted thiourea-functionalized nanoporous silica (FTU-LUS-1) as the sensitive material. Substituted thiourea (FTU) and FTU-LUS-1 were first prepared and then characterized by 1H NMR, 19F NMR, 13C NMR, FTIR, XRD, TG and CNS elemental analysis. The electrodes with FTU-LUS-1 proportion of 10.0 wt% demonstrated very ...
متن کاملCOBALT PHTHALOCYANINE MODIFIED CARBON PASTE ELECTRODE AS A POTENTIOMETRIC SENSOR FOR DETERMINATION OF ASCORBIC ACID
A carbon Paste electrode modified with cobalt (II) phthalocyanine (CoPC) was used as a sensitive potentiometric sensor for determination of ascorbic acid in aqueous solutions. The potential response of the electrode is a linear function of ascorbic acid concentration over the range 5 10 to 10 M (?1- 1800 µg ML ) with a Nernstian slope of 56 mV at pH 7. The limit of detection was 0.2 µg ...
متن کاملPotentiometric determination of trace amounts of amantadine using a modified carbon-paste electrode.
A chemically modified carbon-paste electrode has been described for the sensitive and selective determination of amantadine. Beta-cyclodextrin was used as modifier. The electrode shows a sub-Nernstian response of 51.0 +/- 1.0 mV decade(-1) for amantadine in the concentration range of 6.3 x 10(-10)-7.1 x 10(-7) M at 25 degrees C. The optimum pH value was maintained at 4.5 using a 0.02 M acetate ...

The present study describes the use of a new carbon paste electrode modified by means of Silica nanoparticles prepared by a simple and rapid procedure for the determination of sodium diclofenac (DCF). Moreover, the present study focuses on the characterization of electrochemical impedance spectroscopy (EIS) and scanning electron microscopy (SEM) of the prepared Silica NPs-CPE. In this work, The...
متن کاملPhenylthiourea Modified Highly Ordered Nanoporous Silica for Heavy Metal Ion (Hg2+ ) Trapping
The phenylthiourea-substituted triethoxysilane as a silane agent was synthesized and grafted on highly ordered nanoporous silica (LUS- 1) with a textured morphology and hexagonal array. This material (Tu-LUS-1) contained 0.8 mmol/g of soft base phenylthiourea group and surface area 760 m2 g-1 and was able to adsorb 0.75 mmolHg/g of TU-LUS-1 in endothermic reaction.
