“…The in situ activated bismuth bulk annular band electrode (BiABE, surface: 12.6 mm 2 ) served as working electrode and prepared according to detailed description reported in our previous study. 30 The Ag/ AgCl/3 mol L À1 KCl double junction was used as reference electrode and a platinum wire was used as an auxiliary electrode. The results obtained at the BiABE were then compared with values obtained using hanging mercury drop electrode (HMDE, surface: 1.8 mm 2 ) and the cyclic renewable mercury lm silver-based electrode (Hg(Ag)FE, surface: 6.0 mm 2 ) (both mtm-anko, Kraków, Poland).…”

“…The construction of ex situ activated BiABE and its application for Ni(II) and Co(II) determination have been precisely described previously. 30 The main advantage of this electrode is easy regeneration of its surface by electrochemical activation (E act ¼ À1.9 V, t act ¼ 20 s) in the presence of a tested solution (in situ method) without using of another separate activation cell (Fig. 1).…”

“…Adsorptive stripping voltammetry has been most often utilized for trace, separate and simultaneous nickel and cobalt ions determination in various matrices as this method ensures: high sensitivity, low costs of analysis and relatively short time of measurements. For these determinations various electrodes were used to replace highly toxic mercury electrodes including: bismuth and lead film and bulk electrodes , antimony film electrodes , unmodified glassy carbon , ion exchanger‐modified carbon paste electrodes , carbon microelectrodes modified with metal film or metal microelectrode arrays .…”

This article the first reports on a fabrication and application of an electrochemical three electrode micro‐set containing: in situ plated lead film on carbon fiber working microelectrode, Ag/AgCl reference electrode and a platinum wire counter electrode placed in one casing for simultaneous Ni(II) and Co(II) traces determination by square wave adsorptive stripping voltammetry (SW AdSV). Ni(II) and Co(II) in forms of their complexes with nioxime were accumulated on the lead film plated on a carbon fibers microelectrode during standard procedure of measurement. Thanks to the fact that measurements were performed in micro‐vessel of a volume of 200 μl small amounts of reagents were used to prepare samples for measurements. In addition, because of the use of microelectrode, sample solutions were not mixed during accumulation step of measurements. This fact creates the possibility of conducting fields analysis. The experimental parameters (composition of the supporting electrolyte, potential and time of accumulation) and possible interference effects were investigated. The linear calibration graphs for Ni(II) and Co(II) were in the range from 2×10−9 to 1×10−7 mol L−1 and from 2×10−10 to 1×10−8 mol L−1 for Ni(II) and Co(II), respectively. The correctness of the proposed method was checked by determining Ni(II) and Co(II) in the certified reference material (SPS‐SW1) with satisfactory results.

“…Another advanced preparation of BiEs includes the pre-plating of various electrode substrates with bismuth film or bulk modification of carbon paste. These modifications usually give rise to better sensitivity and selectivity than solid-states electrodes (Baś et al, 2015). The Bi film (BiF) can be usually prepared by in or ex situ electrodeposition processes.…”

The proposed work deals with the utilization of three carbon-based electrode substrates such as boron-doped diamond, glassy carbon and carbon paste for the preparation of in situ bismuth film modified electrodes. Such modified electrodes were subsequently used for the differential pulse anodic stripping voltammetric determination of heavy metal cations (Zn2+, Cd2+ and Pb2+) individually and simultaneously using similar experimental conditions (0.1 mol l−1 acetic buffer solution of pH 4.5 as supporting electrolyte with the addition of 0.1 mmol l−1 Bi3+, deposition potential of −1.4 V and deposition time of 120 s). The results showed that the modification step mostly enhanced the deposition and stripping process of studied cations when compared to the bare electrode substrates. A boron-doped diamond electrode was selected as the substrate for modification and the procedure was applied to the real sample analysis including water sample (certified reference material) and wastewater sample. Using the standard addition method the concentrations of particular heavy metals were quantified and the determined values were in a good agreement with those obtained by the reference method — high resolution atomic absorption spectroscopy with electrothermal atomisation and continual radiation source. This fact highlights that the developed in situ bismuth film modified boron-doped diamond electrode is a suitable electrochemical sensor to be applied to routine analysis of water samples containing heavy metals.
