[ 1 ] - Synergistic Signal Amplification Based on Ionic Liquid-BaTiO3 Nanoparticle Carbon Paste Electrode for Sensitive Voltammetric Determination of Acetaminophen
Monitoring the acetaminophen in biological samples and also in pharmaceutical formulations is important due to the concerns of public health care and drug safety. In this work a carbon paste electrode modified with BaTiO3 nanoparticle (BTO NPs) and room-temperature ionic liquid (IL) (n-hexyl-3-methylimidazolium hexafluoro phosphate) was fabricated. The direct electro-oxidation behavior of aceta...
[ 2 ] - An Electrochemical Sensor Based on Novel Ion Imprinted Polymeric Nanoparticles for Selective Detection of Lead Ions
In this study, the novel surface ion-imprinted polymer (IIP) particles were prepared and applied as a electrode modifier in stripping voltammetric detection of lead(II) ion. A carbon paste electrode (CPE) modified with IIP nanoparticles and multi-walled carbon nanotubes (MWCNTs) was used for accumulation of toxic lead ions. Various factors that govern on electrochemical signals including carbon...
[ 3 ] - Differential Pulse Polarographic Determination of Trace Antimony in Standard Biological Samples after Preconcentration Using 2-Nitroso-1-naphthol-4-sulfonic Acid
A highly selective, sensitive, rapid and economical differential pulse polarographic method has been developed for the determination of trace amounts of antimony in various standard alloys and biological samples after adsorption of its 2-nitroso-1-naphthol-4-sulfonic acid - tetradecyldimethylbenzylammonium chloride on microcrystalline naphthalene in the pH range of 7.5-11.0. After filtratio...

Iron is quantitatively retained on an adsorbent made by coprecipitation of 1,2-dihydroxybenzene-3,5-disulfonic acid (Tiron) and tetradecyldimethylbenzylammonium choride (TDBA) an microcrystalline naphthalene as a slurry or packed in a column, in the pH range 6.0-9.0 from a large volumes of aqueous solutions (up to 200 ml on microcrystalline naphthalene and up to 500 ml of aqueous solutions ...
[ 5 ] - Atomic Absorption Spectrometric Determination of Lead after Extraction and Preconcentration with 5-Br-PADAP
Lead is quantitatively retained on 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (5-Br-PADAP)-ammonium tetraphenylborate with microcrystalline naphthalene or by a column method in the pH range 4.0-6.0 from a large volume of aqueous solutions of various samples with preconcentration factor of 60. After filtration, the solid mass consisting of the lead complex and naphthalene was dissolved wi...
[ 6 ] - Preconcentration of Trace Vanadium with the Ion Pair of 2-Nitroso-1-Naphthol-4-Sulfonic Acid and Tetradecyldimethylbenzylammonium Chloride Onto Microcrystaline Naphthalene and Determination by Derivative Spectrophotometry
Vanadium is quantitatively retained on 2-nitroso-1-naphhthol-4-sulfonic acid tetradecyldimethlbenzyammonium chloride onto microcrystalline naphthalene in the pH range of 3.0-4.0 from a large volume of aqueous solutions of various alloys and synthetic samples. After filtration, the solid mass consisting of the vanadium complex and naphthalene was dissolved with 5.0 mL of dimethylformamide an...
[ 7 ] - Simultaneous Determination of Traces of Lead and Cadmium in Various Samples by Differential Pulse Polarography after Adsorbing Their 1-(2-Pyridyazol)-2-Naphthol onto Microcrystalline Naphthalene
A highly selective, rapid and economical differential pulse polarographic method has been developed for the determination of trace amounts of cadmium and lead present together in various standard alloys and biological samples after adsorption of their 1-(2-pyridylazo)-2-naphthol complexes on microcrystalline naphthalene. Cadmium and lead complexes are equantitatively adsorbed on microcrysta...
