Untreated red seaweed, Kappaphycus alvarezii as a biosorbent to remove Pb(II) ions from aqueous solution / Natalie James Solibun

Present study has been undertaken to propose an alternative use of untreated red seaweed (UTRS), (Kappaphycus alvarezii) as biosorbent for the removal of heavy metal ions from aqueous solutions. The biosorption studies were conducted in batch adsorption system as a function of effect of pH, dosage a...
