摘要：

In this work, the adsorption of Fe(III) onto Brazilian palygorskite nanoparticles was investigated and the modifications of the mineral-aqueous solution interface properties were evaluated. We also investigated the influence of the adsorbent concentration and the best contact time for the adsorption to occur. The results showed that an increase in adsorbent dosage also increased the Fe(III) adsorption and the Langmuir model fitted the experimental data, showing that palygorskite is a potential clay mineral for the removal of cations from solutions.
