چکیده

Acibenzolar-S-methyl (ASM) is a novel fungicide applied for crop protection. A renewable silver amalgam film electrode was used for the determination of ASM in pH 3.4 Britton Robinson buffer using square wave adsorptive stripping voltammetry (SWAdSV). The parameters of the method were optimized. The electroanalytical procedure made possible to determine ASM in the concentration range of 5 10 –3 10 7 molL 1 (LOD=4.86 10 , LOQ= 1.62 10 8 molL ). The effect of common interfering pesticides and heavy metal ions was checked. The validated method was applied in ASM determination in spiked water samples.

Applicability of the silver amalgam electrode in voltammetric determination of zinc and copper in gastric juice and gastric mucosa of rats.

The aim of the work was to compare two analytical methods of trace analysis in respect to their applicability in heavy metals determination in biological samples. Atomic absorption spectrometry (AAS) may be considered as the method of choice in such analyses due to its accuracy, precision and low detection limit. On the other hand, voltammetric methods seem to be as useful, but rarely applied. ...

Voltammetric determination of dinitronaphthalenes using a silver solid amalgam paste electrode.

The electrochemical behavior and application of a new sensor, a silver solid amalgam paste electrode (AgSA-PE), based on the mixture of a fine silver solid amalgam powder (60:40 (w(Hg)/w(Ag))) and a suitable organic pasting liquid (Paraffin oil) in a ratio of 20:1 (w/w), was investigated in an aqueous-methanolic media (1:1). This alternative working electrode provides simple preparation and han...

Comparison Study of Voltammetric Behavior of Muscle Relaxant Dantrolene Sodium on Silver Solid Amalgam and Bismuth Film Electrodes

Voltammetric behavior of muscle relaxant dantrolene sodium (DAN) was studied and the voltammetric methods for its determination using polished and mercury meniscus modified silver solid amalgam electrodes (p-AgSAE and m-AgSAE) as well as using bismuth film electrode (BiFE, ex situ plating on GCE) have been proposed. These working electrodes represent the most commonly used alternatives to mercu...

Electrochemical study of the fungicide acibenzolar-s-methyl and its voltammetric determination in environmental samples.

The electrochemical behavior of new generation fungicide acibenzolar-s-methyl (S-methyl 1,2,3-benzothiadiazole-7-carbothioate, ASM) on the hanging mercury drop electrode (HMDE) was investigated using square wave adsorptive stripping voltammetry. This method of determination is based on the irreversible reduction of ASM at the HMDE. The well-defined ASM peak was observed at -0.4 V (vs. Ag/AgCl) ...

Voltammetric determination of folic Acid using liquid mercury free silver amalgam electrode.

The electrochemical behavior of folic acid (FA) on a polished silver solid amalgam electrode (p-AgSAE), as a liquid mercury free electrode, has been studied in this paper. Differential pulse voltammetry (DPV) was found as a suitable method for voltammetric determination of folic acid. A limit of detection as 5.88 × 10-10 M (after 60 s of accumulation) was calculated for FA determination in an a...
