IONIC LIQUID IMPREGNATED ALGINATE BEADS FOR ADSORPTION OF LEAD

Adsorption of lead metal ion from heavily polluted wastewaters using alginate bead immobilized with ionic liquid can be categorised as a potential biological wastewater treatment method with very less identified hazards. It is essential to separate lead ions from wastewater because lead is a toxic m...
