“…The forward cathodic scan did not exhibit a copper reduction wave; a similar situation was also observed in other studies of the deposition of copper on carbon electrodes and is attributed to the poor electrochemical reversibility of copper [12,19,22,23]. On the other hand, in the reverse anodic scan a sharp anodic peak at 0.1 V was observed.…”

“…The drawbacks of modified electrodes lie with the time-consuming modification process, the low precision and the instability of the sensors. In order to avoid the complexities of modification, different materials have been suggested and tested as mercury-free sensors for the voltammetric determination of copper including screenprinted carbon ink [16], gold [17,18], carbon microelectrodes [19], tungsten [20], PVC-graphite [21], carbon paste [22] and boron-doped diamond [23]. However all of these materials, depending on their nature and properties, have limitations as sensors for stripping analysis.…”

In this work we report a new electrode material formed by injection-moulding of a conducting polymer consisting of carbon fibers in a Nylon matrix. This material is highly conductive, inexpensive, easy to mould in different shapes and requires minimal pretreatment. The electrode was tested as a mercury-free sensor for the trace determination of Cu(II) by anodic stripping voltammetry (ASV). The deposition and stripping behavior of copper on the conducting material was initially studied by cyclic voltammetry and the chemical and instrumental parameters of the determination were investigated. The electrode has been shown to be suitable for the determination of Cu(II) in the range 8 mg L À1 to 30 mg L À1 (with deposition times ranging from 30 s to 10 min) with a relative standard deviation of 2.2% (at the 0.5 mg L À1 level) and a limit of detection of 8 mg L À1 Cu(II) for 10 min of accumulation (at a S/N ratio of 5). The electrode was, finally, applied to the determination of copper in tap-water, pharmaceutical tablets and bovine serum with recoveries of 97.4, 94.9 and 93.4%, respectively

“…When Ag + is added, it binds specically to C-C mismatched base pairs, creating C-Ag + -C base pairs in the DNA double strand. 43,44 An appropriate incubation time aer the addition of Ag + is a key factor in the formation of C-Ag + -C complexes. The PEC response was measured in the range of 20 to 120 min incubation time with the addition of 10 nM Ag + and the results are shown in Fig.…”

A Review of Analytical Techniques for the Determination and Separation of Silver Ions and Its Nanoparticles

Many articles have already been published dealing with silver ions and its nanoparticles, but mostly from the environmental and toxicological point of view. This article is a review focused on the various analytical techniques and detection platforms used in the separation and determination of mentioned above species, especially on the trace concentration level. Commonly used are optical methods because of their high sensitivity and easy automation. The separation methods are mainly used for the separation and preconcentration of silver particles. Their combination with other analytical techniques, mainly inductively coupled plasma mass spectrometry (ICP-MS) leads to very low detection limits of analysis. The electrochemical methods are also powerful and perspective mainly because of the fabrication of new sensors designed for silver determination. All methods may be combined with each other to achieve a synergistic improvement of analytical parameters with an impact on sensitivity, selectivity and reliability. The paper comprises a review of all three types of analytical methods on the determination of trace quantities of silver ions and its nanoparticles.
