enhance the electrode response. In the study by Määttänen et al. (Määttänen et al. 2013 ), electrode modification on low-cost paper-based electrochemical sensors was also successful regarding cyclic voltammetry analysis. There has been some research concerning chemical pre-treatment of the SPEs by NaOH (Wei et al. 2007 , Du et al. 2016 ), which indicated a reduction in the peak-to-peak separation in cyclic voltammetry, suggesting that the electrochemical reversibility was significantly enhanced – possibly due to the removal of polymers/oil binder from the electrode

Abstract

The characteristics of anodic electrochemical dissolution of chalcopyrite (CuFeS2) powder in hydrochloric acid medium with sodium chloride have been studied. Cyclic voltammetry and chronopotentiometry of immobilized microparticles using paraffin-impregnated graphite electrode was employed. Present work is focused on electrochemical identification of chalcopyrite cathodic and anodic reaction products within the potential range of −0.7 to +0.8 V (vs. SCE) in hydrochloric acid solution containing sodium chloride and/or copper(II) chloride.

Abstract

The highly sensitive method of adsorptive stripping voltammetry (AdSV), with differential pulse steps, was performed at a mercury film electrode and has been applied here for the determination of trace molybdenum content in selected wild mushrooms. Fruiting body caps of 12 selected macrofungi species from Basidiomycetes have been investigated. Molybdenum content of investigated samples was determined in the range of 0.006 to 0.38 mg kg−1 of dry matter. The highest value of molybdenum content was found in Leccinum rufum and the lowest in Lactarius deliciosus.
