High efficient removal of chromium (VI) using glycine doped polypyrrole adsorbent from aqueous solution

Author: Ballav, N ; Maity, Arjun ; Mishra, SB Date: Aug 2012 Glycine doped polypyrrole (PPy-gly) adsorbent was prepared via in situ polymerization of pyrrole (Py) monomer in the presence of glycine (gly) for the removal of Cr(VI). Formation of PPy homopolymer and inclusion of gly in the PPy matrix were ... Read more
A method for removal of chromium from chrome dyeing effluent

Author: Roberts, MB Date: Sep 1976 The minimum quantity of chromate necessary for the production of deep colors of high wet fastness on wool is shown for four chrome dyes. Read more
Removal of hexavalent chromium from aqueous solution using polypyrrole-polyaniline nanofibers

Author: Bhaumik, M ; Maity, Arjun ; Srinivasu, VV ; Onyango, MS Date: Feb 2012 Polypyrrole-polyaniline (PPy-PANI) nanofibers as adsorbent of Cr(VI) were prepared without template via coupling of propagating PPy+ and PANI+ free radicals by simultaneous polymerization of Py and ANI monomers in presence of FeCl3 oxidant. ...

Selective removal of Cr(VI) from aqueous solution by polypyrrole/2,5-diaminobenzene sulfonic acid composite

Author: Kera, Nazia H ; Bhaumik, M ; Ballav, N ; Pillay, K ; Ray, Suprakas S ; Maity, Arjun Date: Aug 2016 A polypyrrole/2,5-diaminobenzenesulfonic acid (PPy/DABSA) composite, synthesised by the in situ oxidative polymerization of pyrrole in the presence of DABSA, was studied as an adsorbent for the removal of Cr(VI) from aqueous solution. The ... Read more
