Most of the metal ions are carcinogens and lead to serious health concerns by producing
free radicals. Hence, fast and accurate detection of metal ions has become a critical issue …

Owing to the high toxicity and detrimental effects of chemical contaminants to human health
and the environment, public concerns over chemical contaminants in the environment and in …

Chromium (Cr) appears in nature in two forms: trivalent chromium (Cr (III)) and hexavalent
chromium (Cr (VI)), which have different toxicities. Cr (VI) is generally more toxic and is more …

Chromium exerts serious damage to human beings and to aquatic life and is one of the most
common environmental contaminant and possess toxicity when present above threshold …

In the realm of environmental engineering and water treatment, significant attention has
been devoted to the removal of hexavalent chromium Cr (VI) from wastewater. Delving into …

To investigate critical health effects, a supporting speciation analysis is often matter of
concern in order to identify figure of the bioconcentration or biomagnification of elements like …

The development of screen printed sensors and biosensors is a significant area of
contemporary electroanalysis because of their wide potential possibilities of practical …

Polyaniline/graphene quantum dots (PANI/GQDs) were used to modify a screen-printed
carbon electrode (SPCE) in a flow-based system. A method for rapidly determining the Cr …

Carcinogenic and mutagenic chromium (VI) is a potential hazard to humans and animals.
On the contrary, the trivalent Cr (II) counterpart is a nontoxic essential mineral for humans …

This work presents an easy, highly specific, and sensitive route for the electrochemical
reduction of Cr (VI) by phenosafranine (PSF+) integrated sulfonic acid functionalized …
