Efficient adsorption of Pb2+ from aqueous solutions using papain immobilized on alginate beads

The increasing contamination of water bodies by heavy metals such as lead Pb²⁺ has driven the search for sustainable technologies for their removal. This study proposes the use of papain immobilized on alginate beads (PIPA) as an effective biosorbent for the adsorption of Pb²⁺ from aqueous solutions...
