Recent Chitosan@Magnetite Adsorbents for the Removal of Heavy Metals and Organic Pollutants From Water.

Chitosan@Magnetite composites have gained significant attention in the field of water purification due to their high capacity to absorb contaminants and their ease of separation using magnets. In this review, we reviewed the latest methods for preparing this material and explained its key properties, particularly its structural shape and the ways of modifying it to be more efficient. One of its most obvious advantages is the increase of surface area, which helps improve absorption. To this end, we mentioned several analytical techniques, such as morphology and structure, to understand how this material works. We also explained how this material can remove heavy metals and organic pollutants from water. Finally, we evaluated its performance in terms of absorption capacity, reaction rate, and its ability to be regenerated and reused, confirming its excellent suitability for practical and sustainable water purification.
