Chromium is introduced into the environment by effluents in several industries. It is important
to control this element since it is both toxic and carcinogenic. As its toxicity depends on its …

Main approaches to the trace element analysis of biological fluids and problems appearing
in this case are considered. The specific character of these approaches is illustrated by the …

A novel sensitive, selective, and reversible cobalt (II) ion optical sensor was prepared by the
incorporation of 5-[o-carboxyphenylazo] 2, 4-dihydroxybenzoic acid [CPDB] and sodium …

In this study, N and S co-doped carbon dots (N, S-CDs) were synthesized from biomass,
using sulfamic acid as a passivator. The N, S-CDs have satisfying fluorescence properties …

A simple and rapid dispersive liquid–liquid microextraction procedure based on an ionic
liquid (IL-DLLME) was developed for selective determination of cobalt (Co) with …

A novel Co 2+ selective sensor based on the ionic imprinted polymer (IIP) nanobeads was
constructed and applied for differential pulse cathodic stripping voltammetric determination …

This article reviews the voltammetric methods of chromium determination, including
adsorptive and catalytic adsorptive stripping voltammetry at liquid mercury, metallic films …

The application of the silver amalgam film electrode (Hg (Ag) FE) of prolonged analytical
applicability to the determination of cobalt and nickel by adsorptive stripping voltammetry is …

Development of adsorptive stripping voltammetry (AdSV) combined with in situ prepared
bismuth film electrode (in situ BiFE) on glassy carbon disk surface using diethylenetriamine …

Chromium (Cr) is a very important element examined for last decades on many expert fields.
Its toxicity, mobility and bioavailability are strongly dependent on its oxidation state, Cr (III) …
