Synthesis and characterization of thiolated chitosan beads for removal of Cu(II) and Cd(II) from wastewater
Removal of Cu(II) and Cd(II) from wastewater using porous chitosan beads is likely to be enhanced by the introduction of thiol groups (-SH). This is because, in accordance with the Hard Soft Acid Base concept, the soft Lewis base of -SH forms a strong bond with soft Lewis acid of Cd(II) or with bord...
