Single and Binary Removals of Pb(II) and Cd(II) with Chemically Modified Cladodes.

In this study, cladodes of (OFIC), chemically modified with NaOH (OFICM), have been prepared, characterized, and tested as an effective biomass to remove Pb(II) and/or Cd(II) from aqueous media. At an optimum pH of 4.5, the adsorption capacity, q, of treated OFICM was almost four times higher than that of untreated OFIC.
