Conducting polymers (CPs), thanks to their unique properties, structures made on-demand,
new composite mixtures, and possibility of deposit on a surface by chemical, physical, or …

Remediation of chromium-containing wastewaters is of special concern due to its toxicity
and persistence in the environment. For chromium removal, various physicochemical as well …

In this Article, bulk-quantity one-dimensional polyaniline (1D PANI) nanowire/tubes with
rough surface were prepared by a simple chemical oxidation method. This kind of PANI …

Capsular polypyrrole hollow nanofibers (PPy-HNFs) were fabricated via in situ
polymerization of pyrrole on an organic–inorganic template, followed by acid etching. Their …

The voltammetric behavior of hexavalent chromium species (Cr (VI)) was respectively
studied at ITO, bulk Au, and Au-electrodeposited electrodes in 0.01 M NaCl aqueous …

Various oxidation states of polyaniline, as film and powder, were used for reduction of highly
toxic Cr (VI) to less toxic Cr (III) ion. The effects of various parameters such as synthesis …

Adsorption is one of the most commonly used methods for the remediation of heavy metals.
Generally, the spent adsorbent is regenerated using chemicals. Although chemical …

Studies of pollution due to hexavalent chromium are important because it represents a risk
to human health and the environment. Hexavalent chromium is a toxic substance and has …

Polypyrrole (ppy)-modified electrode was used for electroreduction of Cr (VI) and showed
favorable advantage with extremely higher removal percentage and current efficiency over …

Hexavalent chromium [Cr (VI)] is highly toxic, carcinogenic, and mutagenic to living
organisms. In this paper, the reduction of Cr (VI) to the much less toxic trivalent state [Cr (III)] …
