This article reviews the electrochemistry and electroanalytical applications of carbon paste‐
based electrodes, sensors, and detectors on the occasion of the half‐of‐century anniversary …

Inorganic arsenic, a term which encompasses both As (III) and As (V) species, constitutes
the highest toxicological risk associated with arsenic in water in contrast to the organic …

In this review (with 500 refs), both electrochemistry and electroanalysis with carbon paste-
based electrodes, sensors, and detectors are of interest, when attention is focused on the …

It is known that arsenic has different toxicological properties dependent upon both its
oxidation state for inorganic compounds, as well as the different toxicity levels exhibited for …

In this work, we demonstrate the preparation of hybrid thin films based on double-walled
carbon nanotubes and graphene for electrochemical sensing applications. The hybrid films …

The knowledge of metal ion speciation is essential for predicting the exact toxicities of metal
ion species in the environment. Metal ions can exist in various oxidation states, each of …

This paper provides a review that summarizes several examples of the literature from 1980
to 2003, to illustrate the applications of stripping potentiometry for the determination and …

A electrochemical biosensor for As (III) determination has been developed by immobilization
of the Alcaligenis faecalis bacteria on gold nanoparticle–modified screen–printed carbon …

Voltammetric approaches for the determination of arsenic and speciation at trace levels are
critically appraised in a review covering the literature from 1970 to 2002. Special attention is …

A new, simple, and selective method has been presented for the separation and
preconcentration of inorganic arsenic (As (III)/As (V)) and selenium (Se (IV)/Se (VI)) species …
