Abstract

Micron sized Fe(II)-silicate precipitation tube (FeIISPT) synthesized through
'silica garden' route has been characterized by different analytical techniques. These
tubes are hollow, porous and hierarchially built from smaller tubules of 5-10 nm diameter.
Morphology and chemical composition at the interior and exterior surface of these tubes
differ remarkably. FeIISPT comprises significant amount of physically and chemically
bound moisture. The isoelectric point of FeIISPT may be observed at pH 4.01 indicating
the surface bearing surplus negative sites. FeIISPT appears to be a potential adsorbent
of Hg(II), Zn(II), Pb(II) and Cd(II). Physico-chemical properties of FeIISPT have been
compared with FeIIISPT.
