A study on the simultaneous determination of Ni(II) and Co(II) dimethylglyoximates (Ni-DMG and Co-DMG) through adsorptive cathodic stripping voltammetry at an in situ bismuth-modified gold electrode (Bi-AuE) is reported. The key operational parameters, such as Bi(III) concentration, accumulation potential and accumulation time were optimized and the morphology of the Bi-microcrystals deposited on the Au-electrode was studied. The BiAuE allowed convenient analysis of trace concentrations of solely Ni(II) or of Ni(II) and Co(II) together, with cathodic stripping voltammograms characterized by well-separated stripping peaks. The calculated limit of detection (LOD) was 40 ng L À1 for Ni(II) alone, whereas the LOD was 98 ng L À1 for Ni(II) and 58 ng L À1 for Co(II), when both metal ions were measured together. The optimized method was finally applied to the analysis of certified spring water (NIST1640a) and of natural water sampled in the Lagoon of Venice. The results obtained with the BiAuE were in satisfactory agreement with the certified values and with those provided by complementary techniques, i.e., ICP-OES and ICP-MS.

“…The GCE modifiers in common use are metals (mercury , gold [81][82][83][84][85], cadmium [87], copper [88], lead [89], platinum [90], bismuth [91][92][93][94][95][96]) and facilitating the precipitation of amalgam-forming and electropositive elements. Organic substances (OS) [107][108][109][110][111][112][113][114][115][116][117][118][119][120][121], macrocyclic compounds [122][123][124][125][126], polymers [127-131, 157-159, 165-166, 169-175], bioactive compounds [186], and nanotubes [187][188][189][190] can also serve as GCE modifiers.…”

Papers dealing with modified electrodes made of carbon materials and composites for use in stripping voltammetry of metals have been reviewed. The review consists of two parts, of which the first considers applications of modified glassy carbon and carbon paste electrodes, while the second describes diverse modified carbon-containing composite and microscopic electrodes. Information about modifiers, electrode modification methods, conditions, and limits of detection of elements in different materials has been tabulated. The review covers 550 papers published in Russia and abroad between 1990 and the first half of 2007.

“…The detection limit was given by the equation C L = 3S bl /S, where S bl is the standard deviation of the blank measurements and S is the sensitivity of the calibration graph. The detection limit of Co 2+ for 60 s accumulation was calculated to be 44 pM, which is lower than that at hanging mercury drop electrode [2,16], stationary mercury drop electrode [37], cylindrical silver-based renewable amalgam film electrode [13,38], in situ and ex situ plated bismuth film electrode [39][40][41][42], solid bismuth disk vibrating electrode [43], in situ plated lead film glassy carbon electrode and screen-printed electrode [9,27,28], and in situ plated leadcopper film electrode [30].

“…For the bismuth film and tinbismuth film electrode, when they are used in AdSV analysis where alkaline solutions are typical supporting electrolytes, it is inconvenient because of the risk of hydrolysis of Bi 3+ species [23,26] which limits its practical applications. Then, some concerns were focused on lead film electrode [27][28][29] and lead-copper film electrode [30]. Lead can be stabilized easily at mild alkaline pH, but it is widely known as a toxic metal.…”

Tin-bismuth alloy electrode (SnBiE) was used for trace cobalt determination for the first time. Compared to the bismuth bulk electrode, the SnBiE possesses the advantages of higher hydrogen overpotential, easier manufacture, and lower cost. In addition, there is no need for a pretreatment (in terms of modification) of the electrode before measurements. The analysis of Co(II) was made by the adsorptive accumulation of the cobalt-nioxime complex from solution containing 60 μM nioxime and 0.1 M ammonia at pH 9.4 and followed by the reduction of the accumulated complex. The electroanalysis results show that the optimal sensitivity can be obtained by using nitrite as the auxiliary reagent. The calibration plot for Co(II) quantification was linear from 0.2 to 20 nM with a correlation coefficient of 0.998. Meanwhile, a detection limit of 44 pM was obtained in connection with an accumulation time of 60 s, which is more sensitive than that of the mercury, bismuth, lead, and lead-copper electrodes. The practical applications of SnBiE have been performed for the determination of Co(II) in real water samples, and the results are consistent with those results by use of inductively coupled plasma-mass spectrometry (ICP-MS).
