Resumen
"Nanoscale iron oxide particles were synthesized and deposited on porous alumina tubes to
develop tubular ceramic adsorbers for the removal of arsenic, which is an extremely toxic
contaminant even in very low concentrations. Its natural presence affects rural and
low-income populations in developing countries in Latin America and around the world,
which makes it essential to develop a user-friendly, low energy demanding and low cost
treatment technology. The fabricated ceramic membranes can be operated with minimal
trans-membrane pressure difference and do not require pumping. The support tubes and
final membrane have been characterized by surface area and porosity measurements,
permeability tests and scanning electron microscopy (SEM) imaging. Arsenic concentrations were determined by inductively coupled plasmaeoptical emission spectroscopy
(ICP-OES). Due to its low cost and simple operation, the system can be applied as a point of
use device for the treatment of arsenic contaminated groundwaters in developing
countries."
