The bismuth film is a great promise as a suitable material to replace the mercury electrodes due to its low toxicity and good cathodic potential range. This work studies the influence of the electrodeposition conditions ...

Scanning electrochemical microscopy (SECM) in feedback mode was employed to characterise the reactivity and microscopic peculiarities of bismuth and bismuth/lead alloys plated onto gold disk substrates in 0.1 molL(-1) NaOH ...

Environmental contextElectroanalytical methods have found wide application in trace metal speciation analysis in environmental systems. The need to find functional alternatives to mercury electrodes for in situ speciation ...

Propolis is a honeybee product which contains lead as one of the main contaminants. Taking into account that this product is used in the food industry, the Código Alimentario Argentino establishes maximum allowable level ...

Raw propolis and bee pollen has been widely used in different areas such as medicine, food and apitherapy because they have biological and medicinal properties. The beneficial effects of both bee products for human health ...

In this study the multivariate optimization of bismuth film deposition (BiFE) on glassy carbon electrode, together with square wave voltammetry parameters for nitrophenol quantification, is described for the first time. ...

A rapid and simple square wave voltammetry method (SWV) for atrazine determination with bismuth film electrode using chemometrics was developed. Different variables such as buffer pH and SWV frequency, pulse height and ...
