摘要: Abstract The non-magnetic TiO 2 powder and magnetically modified were employed for the sorption experiments. FeSO 4 .7H O was used synthesis of responsive . prepared magnetic materials characterized by scanning electron microscopy X-ray diffraction methods. particle size specific surface area determined. A detailed study adsorption process performed using batch experiments carried out with various concentrations lead ions contact time. flame atomic absorption spectrometer determination Pb 2+ concentration in solution. Adsorption has been modeled Langmuir Freundlich isotherms linear non-linear regression. results showed that on particles occurred a monolayer. Presence iron oxides sorbents increased rate, maximum amount adsorbed per mass comparison particles. allow separation already pollutants.
