1. Chitosan biopolymer as an adsorbent for drinking water treatment : Investigation on Arsenic and Uranium
Abstract : In many countries over the world (including Sweden), metal toxicity in freshwater resources causes a severe drinking water quality problem and poses a threat to the environment and human health. Among the different toxic metals in the water resources of Sweden, arsenic and uranium are the biggest threats to health. READ MORE

4. Adsorption of Metallic Ions onto Chitosan : Equilibrium and Kinetic Studies
Abstract : Equilibrium isotherms and the adsorption kinetics of heavy metals onto chitosan were studied experimentally. Chitosan, a biopolymer produced from crustacean shells, has applications in various areas, particularly in drinking water and wastewater treatment due to its ability to remove metallic ions from solutions.
