“…Different working electrodes are used in voltammetric determination of lead. These include hanging mercury drop electrode (HMDE) [17] [29]. The hanging mercury drop electrode is the most common because of its analytical properties in the cathodic range; however, health considerations and safety regulations limit its application because of its N.

This study presents the elaboration of a simple and cheap electrode made by carbon paste introduced into a cavity of electrode body, and used for the lead traces determination in tap water. A potentiostatic pre-electrolysis at constant voltage enables the reduction of the lead (Pb 2+ ) and the accumulation of the metallic lead at and into the carbon paste; the reoxidation of the Pb (Linear sweep voltammetry) leads to the anodic striping peak. The effect of the main operating parameters on the shape of the peak and the magnitude of the current was examined and their optimal values were determined. Then calibration was achieved and the method was successfully applied (using all the optimized parameters) to the determination of lead in water, with a detection limit of 0.138 µg•L −1. Compared to other methods (ICP-AES for example), the proposed method offers a satisfactory detection limit of the Pb 2+ (0.138 µg•L −1

Visual Colorimetry for Trace Antimony(V) by Ion-Pair Solid-Phase Extraction with Bis[2-(5-chloro-2-pyridylazo)-5-diethylaminophenolato]cobalt(III) on a PTFE Type Membrane Filter

et al. 2008

A new visual colorimetry for trace antimony(V) based on ion-pair solid-phase extraction to a PTFE-type membrane filter with bis[2-(5-chloro-2-pyridylazo)-5-diethylaminophenolato]cobalt(III) ion ([Co(5-Cl-PADAP)2] + ) has been developed. Experiments showed that hexachloroantimonate(V) ion (SbCl6 -) was adsorbed with [Co(5-Cl-PADAP)2] + to the front surface of the PTFE filter. The adsorption of antimony(V) ion was promoted by the addition of lithium chloride as a source of chloride ion. The excess reagent of [Co(5-Cl-PADAP)2] + was eluted by rinsing with a 10 wt% methanol aqueous solution. In this case, the slow rate of the hydrolysis reaction of SbCl6 -and the difference of the hydrophobicity of the ion pairs were important for adsorption and separation with a PTFE-type membrane filter. The antimony(V) concentration was determined through a visual comparison with a standard series. The visual detection limit was 0.10 μg. The calibration curve assessed with the reflection spectrometric responses at 580 nm was linear in the concentration range of 0.10 -1.2 μg (r = 0.996). The proposed method has been applied to the determination of sub-microgram levels of antimony(V) ion in water samples.

Determination of Antimony in Steel by Differential Pulse Anodic Stripping Voltammetry at a Rotating Gold Film Electrode

The accurate determination of antimony in steel is important to the steel industry, because grain boundary segregation of antimony causes the decrease in toughness of steel owing to the temper embrittlement. Spectrometric methods 1,2 are commonly used for the determination of antimony in iron and steel, but they require a preconcentration procedure, which generally involves much skill, labor or time, and the use of toxic organic solvents such as toluene, 1 to avoid any interference from iron matrix. Furthermore, the methods exhibit poor sensitivity.Stripping voltammetry is a powerful electroanalytical technique for the determination of trace antimony and has been extensively applied in studying antimony in various samples. It includes anodic stripping voltammetry (ASV) at mercury, [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] Only a few papers have been published to date on the stripping voltammetric determination of antimony in steels. [33][34][35] Wang et al. 33 and Hofbauerova et al. 34 used ASV at mercurybased electrodes in a hydrochloric acid-alcohol medium for the determination of antimony in steels. Zhou et al. 35 developed 1.5th-order derivative linear-sweep adsorptive stripping voltammetry of antimony(III) complexed with morin (2′,3,4′,5,7-pentahydroxyflavone) at a static mercury drop electrode. However, those methods involve a troublesome procedure such as filtration or require a time-consuming and laborious standard additions method because of removing interferences from coexisting elements. Furthermore, mercury, which is toxic and difficult to use, is employed exclusively as the working electrode.The present paper describes a simple, rapid and accurate method for the direct determination of antimony at trace levels in steel based on ASV of antimony(III) at a gold film electrode without any preconcentration step. Experimental ApparatusVoltammetric determinations were performed using a BAS-50W electrochemical analyzer with an RDE-1 rotating disk electrode (Bioanalytical Systems, West Lafayette, IN, USA) and a BJC-240J printer (Canon, Tokyo, Japan). A platinum wire was used as a counter electrode. A saturated calomel reference electrode (SCE) was connected to a glass voltammetric cell (25 mm×22 mmφ) by a 4% agar-saturated potassium nitrate bridge. ReagentsKanto Chemicals "Ultrapure" grade mineral acids were used throughout, and other chemicals were of analytical-grade without further purification. Water was distilled from a vitreous silica sub-boiling still. An acid mixture solution was prepared by mixing one volume of 10 mol dm -3 nitric acid and one volume of 10 mol dm -3 sulfuric acid. Standard antimony(III) solutions were prepared daily by diluting a commercially available stock standard solution (1 mg cm -3 of animony(III) in 2.5 mol dm -3 hydrochloric acid) to the desired concentration with the acid mixture solution. Preparation of gold plated glassy-carbon electrodeThe surface (7 mm 2 area) of a glassy carbon disk electrode (Bioanalytical Systems) was polished to a mirror fin...
