“…Recently, polymer modified electrodes gained great interest due to their good stability, reproducibility, more active sites, homogeneity in electrochemical deposition [ 138 ], and improved response characteristics [ 156 ]. One of the most used technique for covering the electrode surfaces with polymeric films is electropolymerization; it can be realized by cyclic voltammetry [ 34 , 59 , 66 , 114 , 118 , 121 , 122 , 130 , 138 , 156 , 168 , 170 , 173 , 175 , 207 , 208 ], by applying a constant potential [ 41 , 112 , 183 ] or a constant current [ 62 , 153 , 172 , 178 ] to the bare or previously modified PGE immersed in the solution containing monomer and eventually other components. A dip-coating method was applied to modify a PGE from a casting solution containing carmoisine/polyaniline or copper-carmoisine complex/polyaniline [ 129 ].…”

“…In order to demonstrate the modification of a surface, different techniques are used to investigate and to compare the morphology and/or the electrochemical characteristics of the respective surface and/or of the modifier, before, during, or after the modification process. For surface morphology of bare or modified PGE investigations, different techniques of electron [ 3 , 15 , 24 , 28 , 29 , 32 , 34 , 35 , 54 , 60 , 65 – 67 , 85 , 111 , 118 – 122 , 126 – 128 , 130 , 135 , 141 – 143 , 145 – 148 , 158 , 161 , 170 , 173 , 175 , 178 , 181 – 183 , 189 , 198 , 200 , 204 , 205 , 210 , 216 , 218 , 219 ] and atomic force microscopy [ 28 , 29 , 60 , 65 – 67 , 112 , 126 , 172 , 198 , 205 ] are widely used. Sometimes, scanning electron microscopy (SEM) was coupled with energy-dispersive X-ray spectroscopy analysis [ 130 , 143 , 149 , 152 , 156 , 172 , 187 , 188 , 203 – 205 ].…”

Due to their electrochemical and economical characteristics, pencil graphite electrodes (PGEs) gained in recent years a large applicability to the analysis of various types of inorganic and organic compounds from very different matrices. The electrode material of this type of working electrodes is constituted by the well-known and easy commercially available graphite pencil leads. Thus, PGEs are cheap and user-friendly and can be employed as disposable electrodes avoiding the time-consuming step of solid electrodes surface cleaning between measurements. When compared to other working electrodes PGEs present lower background currents, higher sensitivity, good reproducibility, and an adjustable electroactive surface area, permitting the analysis of low concentrations and small sample volumes without any deposition/preconcentration step. Therefore, this paper presents a detailed overview of the PGEs characteristics, designs and applications of bare, and electrochemically pretreated and chemically modified PGEs along with the corresponding performance characteristics like linear range and detection limit. Techniques used for bare or modified PGEs surface characterization are also reviewed.

“…2,3 It is present in low quantities (10 À5 to 10 À3 M) in wash streams coming out from nuclear reactors both in aqueous and nonaqueous media and, as such, constant monitoring of these streams for the presence of uranium in high activity content is essential. 3 Many methods have been developed for the determination of uranium, based on different techniques, such as ion selective electrodes, 4,5 nuclear techniques, 6 inductively coupled plasmamass spectrometry, 7,8 electrochemistry, 9-11 uorimetry 12,13 and spectrophotometry. [14][15][16] These methods are either time consuming, involving multiple sample manipulations or too expensive for most analytical laboratories.…”

A highly selective and sensitive fluorescent sensor for the determination of uranyl ion is developed. The\ud sensing membrane was prepared by incorporating 5-(9-anthracenylmethyl)-5-aza-2,8-dithia[9],(2,9)-1,10-\ud phenanthrolinophane as fluoroionophore in the plasticized poly(vinyl chloride) membrane containing 2-\ud nitrophenyloctylether as plasticizer. The proposed sensor displays a wide linear response range of 1.0 x\ud 10-10 to 1.0 x 10-3 M with a low limit of detection of 2.7 x 10-11 M in solution at pH 4.0. This sensor has\ud a relatively fast response time of less than three min. In addition to high stability and reproducibility, it\ud shows a unique selectivity towards uranyl ion with respect to common coexisting cations. The sensor can\ud be regenerated by exposure to a solution of ethylene diamine tetraacetic acid. The proposed sensor was\ud then applied to the determination of uranyl in water samples with satisfactory result

“…Organophosphorous compounds/or their metal ion-pairs are prominent among the extractants which have been extensively used for developing uranyl ion-selective electrodes [35][36][37][38]. Uranium selective electrodes based on some commercial organophosphorous extractants of uranium such as trioctylphosphine oxide [39], tris(2-ethylhexyl)phosphate [40], cyanex extractants [41] and bis(2-ethylhexyl)phosphate [42] have been reported.…”

The construction and performance characteristics of poly(vinyl chloride) membrane electrodes for uranyl ions based on dibutyl butyl phosphonate (L1) and di-n-octyl phenyl phosphonate (L2) as ionophores, are reported. The optimized membrane electrodes based on L1 and L2 exhibited a Nernstian response for uranyl ions over a concentration range of 5.0 9 10 -6 -1.0 9 10 -1 and 5.5 9 10 -5 -1.0 9 10 -1 mol L -1 in the pH range 2.1-3.4, with slopes of 28.6 and 29.7 mV decade -1 , respectively. The optimized electrodes exhibit good selectivity for UO 2 2? ions over a wide variety of other metal ions. The electrodes exhibit a fast dynamic response of *30 s. The developed sensors were used for potentiometric determination of uranyl ions concentration in different real samples and the obtained results agreed well with those obtained employing inductively coupled plasma optical emission spectrometer.
