Abstract
The sorption of Ni from aqueous solution using fly ash, CaCO3 and sawdust preparations from pine (Pinus roxburghii) and cedar (Cedrus deodara) was investigated. Fly ash with a total of 90% Ni removal, was superior to CaCO3 (55%), sawdust from cedar (63%) or pine (41%) within 30 min. Fly ash was also an effective sorbent for Cd (79%) and Cu (75%). Ni was sequestered significantly by the dead biomass of Pseudomonas (60%) or Nostoc (41%) or Rhodopseudomonas (35%). Freundlich constants (KF) based on the Freundlich isotherm of all the sorbents were in the sequence: fly ash (213·8)>Pseudomonas (169·8)>Nostoc (131·8)>sawdust from cedar (64·57)>CaCO3 (56·23)>Rhodopseudomonas (51·29)>sawdust from pine (44·67). The observations indicate the possible cost-effective deployment of fly ash, carbonates of calcium and plant parts with native resins as metal sorbents
