The Use of Magnetic Nanomaterials for the Retaining of Cu(II) Ions out of Residual Water

Résumé

In the developed countries the removal of hard materials from residual waters using advanced technologies such as ionic change, precipitation, ultrafiltration or electrochemical deposits seems inconvenient from the economic point of view for the industry because its high costs. Therefore, it is necessary to introduce new technologies that imply low costs.
By linking chitosan and magnetite particles (Fe₃O₄), a new magnetic adsorbent with 100-200 nm particles and of great efficiency to move off the metalic ions is obtained. That is why this study aims to obtain a new magnetic material with great efficiency to retain copper out of synthetic solutions, and then to compare it, from the retaining point of view, with simple synthesized magnetide (Fe₃O₄).
