In this work, we design pellets of a nano-functionalized non-conventional
adsorbent materials for the removal of Cr in drinking water. The nonconventional
materials are attracting interest on this applications in the last
years, due to some specific properties, as they are plentiful, inexpensive, and in
most of the cases, locally available. The used materials for this project are red
mud, fly ash, Iron wool, with some common characteristic, all are formed by
metal oxides, which has been showed to have good affinity for adsorption of
heavy metals. The functionalization was made with Fe 3 O 4 nanoparticles, in order
to improve the adsorbent properties due to the increasing the active sites
available for the adsorption of the heavy metal ions. The composite materials
was tested in a simulated contaminate solution, containing different amounts
of heavy metals ions, Chromium. The characterization surface techniques used
over this composite materials include SEM, with EDX analysis, TEM and XRD,
before and after the exposure in the simulated experimental solution. SEM and
XRD characterization results shows the presence of different metal oxides in the
absorbent material; and in the pellets surface, is possible to observe the
presence of micro and macro porous distributed over it, which as haven and
effect in the adsorption of the heavy metals. Also, different analytical techniques
like ICP-Mass spectrometry analysis, and TOC analysis was used to know the
percentage of the heavy metal removal.
