Simple, rapid, and efficient water purification by chitosan coated magnetite nanoparticles.

Chitosan coated magnetite nanoparticles were prepared and used as adsorbent, chelating agent or bactericidal agent to remove organic contaminants, heavy metals, and bacteria from water. The method is simple and rapid. The obtained results are promise, where the prepared particles able to remove more than 90% and 60% from organic and inorganic contaminants respectively. Also chitosan coated magnetite nanoparticles inhibited the bacterial growth at concentration 2% w/v.
