Insights into recent advances of chitosan-based adsorbents for sustainable removal of heavy metals and anions

With globally increased human population and industrialization, the natural sources of water are reduced and then contaminated. Therefore, development of advanced technologies for the efficient water treatment is becoming of the scope of each of the nation. One of the cost-effective and well-known t...
