Abstract :
To remove arsenic from water we are developing a research project that applies magnetic separation methods. In order to increase the removal efficiency we are using magnetic aggregates. These magnetic aggregates are iron-based and were all (except for one) prepared by us. In this paper we report the preparation steps and some of the results of the characterization and absorption tests we have performed in order to conclude about its structure and efficiency in what concerns arsenic removal.
