Dehalogenation of aromatic halides by polyaniline/zero-valent iron composite nanofiber: Kinetics and mechanisms

Author: Giri, S ; Bhaumik, M ; Das, R ; Gupta, VK ; Maity, Arjun Date: Mar 2016 Dehalogenation of aryl halides was demonstrated using polyaniline/zero valent iron composite nanofiber (termed as PANI/Fe0) as a cheap, efficient and environmentally friendly heterogeneous catalyst. The catalyst was prepared via rapid mixing ... Read more
An efficient selective reduction of nitroarenes catalyzed by reusable silver-adsorbed waste nanocomposite

Author: Giri, S ; Das, R ; Van der Westhuyzen, Christiaan W ; Maity, Arjun Date: Jul 2017 Silver nanocomposites (AgNCs) were produced by adsorption onto an electron-rich polypyrrole-mercaptoacetic acid (PPy-MAA) composite, known to be a highly efficient adsorbent for the removal of Ag+ ions from aqueous media in the remediation ...

Removal of toxic pollutants from aqueous media using poly (vinyl imidazole) crosslinked chitosan synthesised through microwave assisted technique

Author: Midya, L ; Das, R ; Bhaumik, M ; Sarkar, T ; Maity, Arjun ; Pal, S Date: Apr 2019 Water contamination owing to the presence of toxic organic chemicals/heavy metals are considered to be one of the serious global environmental issues. Various advanced polymeric materials have been developed and used for the separation/removal ... Read more
Silver decorated magnetic nanocomposite (Fe3O4@PPy-MAA/Ag) as highly active catalyst towards reduction of 4-nitrophenol and toxic organic dyes

Author: Das, R ; Sypu, VS ; Paumo, HK ; Bhaumik, M ; Maharaj, V ; Maity, Arjun Date: May 2019 Developing innovative technologies for the efficient treatment of wastewater containing toxic organic pollutants is of particular importance worldwide. Removal of organic contaminants from aqueous media through chemical reduction using noble ... Read more
Thiol-modified magnetic polypyrrole nanocomposite: An effective adsorbent for the adsorption of silver ions from aqueous solution and subsequent water disinfection by silver-laden nanocomposite

Author: Mahlangu, Thembisile P ; Das, R ; Abia, LK ; Onyango, M ; Ray, Suprakas S ; Maity, Arjun Date: Jan 2019 A magnetic nanocomposite (NC), Fe3O4@PPy-MAA, was synthesised via in situ oxidative polymerisation of the pyrrole monomer in a thioglycolic acid (mercaptoacetic acid) solution (as a dopant), in the presence of iron oxide (Fe3O4). The newly ... Read more
