“…By analysing CV and CPSV data, it is suggested that at the Pt surface, a stepwise (As(III)As(IV)As(V)) process is involved in the acidic pH ( e.g. [3][4][5], meanwhile, the mechanism is concerted in the neutral and basic medium. Based on CV and EIS data, it is suggested that different types of oxide species, on platinum surface at different pH values, play roles to determine the reaction mechanism.…”

“…It subsists in the nature using four different oxidation states +V (arsenate), +III (arsenite), 0 (arsenic), and −III (arsine) [1]. Concerning toxicity, inorganic arsenic (arsenite) is one of the most notorious carcinogens over the glove [1][2][3][4][5][6][7][8][9][10]. The extreme water solubility of arsenite ions is responsible for its widespread presence in the underground water.…”

“…The extreme water solubility of arsenite ions is responsible for its widespread presence in the underground water. They enter into the natural water systems from natural earth deposits or from industrial and agricultural wastes [4]. In particular, the existence of extremely high As(III) concentrations in Bangla delta (Bangladesh and West Bengal, India) ground waters could be due to the reductive dissolution of hydrous ferric oxide by iron-reducing bacteria [5].…”

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.
