“…The superhydrophobic properties of coatings are also in interest of scientists [43]. Research groups have been collaborating with international groups from Germany [44][45][46][47], Japan [48][49][50][51][52], France [53], Algeria [54] [87][88][89][90][91] is also an important issue for scientists. The topic of SOFC [92] is explored as well.…”

The electrochemistry research team activity from Poland is marked by significant increase in the last 20 years. The joining of European Community in 2004 gives an impulse for the development of Polish science. The development of electrochemistry has been stimulated by cooperation with industry and the establishment of technology transfer centers, technology parks, business incubators, etc. and the mostly by simplified international collaborations. Five research institutions from Krakow reports work in the field of electrochemistry. The achievements of all teams are briefly described.

“…In this context, the appropriate baseline subtraction method is of great relevance. Different algorithms for baseline subtraction have been proposed [97][98][99] and the software of modern electrochemical instruments includes integrated routines to perform this task. Figure 4B illustrates how appropriate definition of the baseline affects the current to be measuredthe same is applicable for peak areas -using ASV as an example.…”

Electrochemical stripping analysis (ESA) is a trace electroanalytical technique for the determination of metal cations, inorganic ions, organic compounds and biomolecules. It is based on a pre-concentration step of the target analyte(s), or a compound of the target, on a suitable working electrode. This is followed by a stripping step of the accumulated analyte using an electroanalytical technique. Advantages of ESA include high sensitivity and low limits of detection, multi-analyte capability, low cost of instrumentation and consumables, low power requirements, potential for on-site analysis, speciation capability and scope for indirect biosensing. This Primer covers fundamental aspects of ESA and discusses methods of pre-concentration and stripping, instrumentation, types of working electrodes and sensors, guidelines for method optimization, typical applications, data interpretation and interferences, and method limitations and workarounds. Finally, the current trends and future prospects of ESA are highlighted.

“…In order to solve the abovementioned issue instrumental, chemical and mathematical approaches are reported. Among them: elimination of capacitive current [9], lowering the background current [10,11], increasing the analytical signal as a result of employing catalytic processes [12][13][14], enhancement an analyte transport to the electrode surface by means of vibrating electrodes [15][16][17] or ultrasounds [18][19][20], analytes preconcentration at very negative potentials [21,22], application of interdigitated microelectrode arrays [23] or ring-disk electrode [24] and other ways [25] were reported.…”

The article reviews an application of double deposition/accumulation and stripping steps as a new and beneficial manner of decreasing a detection limit and/or interferences elimination in stripping voltammetric determination of inorganic ions: Pb(II), Cd(II), Tl(I), U(VI), Au(III), As(III), Se(IV), In(III), Co(II), Cu(II), Bi(III) and Ga(III). A simple design of four‐electrodes system, containing two working electrodes differing in their surface area, allows for conducting two preconcentration and two stripping steps in one measurement cycle and in one voltammetric cell. Considerable analytes preconcentration and, consequently, an increase of sensitivity of determinations was obtained by conducting the first stripping step in a small volume of a solution near the microelectrode surface. An appropriate selection of the conditions of the first deposition/accumulation and the first stripping steps allowed for a minimization/elimination of interference effects. The proposed procedures allows for ultra‐trace levels determinations of mentioned inorganic ions (often impossible to determine by means of traditional three‐electrodes systems) without additional preconcentration outside the electrochemical cell and with the use of mercury‐free electrodes.
