Universidad Nacional de Córdoba; Argentina.The presence of arsenic in water used for human
consumption is a widespread problem in several regions around the world. Cordoba Province at the
center of Argentine has aquifers that naturally contain As and are the main source of drinking water for
dispersed rural population.
Due to health issues generated by the natural presence of arsenic in aquifers, different remediation
techniques have been developed in recent decades
for the removal of this compound from water. Available alternatives for arsenic removal include chemical oxidation, precipitation, coagulation, reverse osmosis, adsorption, biological degradation and
electrokinetic (Litter et al., 2010). However, adsorption was preferred in many cases due to its low cost
and the wide range of reactive materials that may be
used for arsenic retention (Mohan and Pittman,
2007; Maji et al., 2008; Jovanović y Rajaković,
2010; Carro Perez and Francisca, 2013a). The adsorbing surfaces or reactive media usually includes
activated alumina, iron-based media or other oxides,
bauxite, hematite, feldspar, laterite, clay minerals
(eg. bentonite and kaolin), activated carbon, cellulosic material, blast furnace slag, surfactant modified
zeolite and ion exchange resin, among other.
In this work, a low cost natural material is characterized with the purpose of assessing its sorbent capacity. Available batch and column tests experimental
results are used for the development and calibration
of a domestic filter for the removal of As in drinking
water.Fil: Francisca, F.M. Universidad Nacional de Córdoba. Consejo Nacional de Investigaciones Científicas y Técnicas; Argentina.Fil: Carro Perez, M.E. Universidad Nacional de Córdoba.
