Several characteristics of natural diatomites from Dragovishtitsa and Ignatievo deposits (Bulgaria) such as chemical composition, surface area, pore volumes, XRD and IR spectra were studied. The sorption properties of the diatomites towards Fe3+, Pb2+, Cu2+, Cd2+, Tl+, Mn2+, Ni2+ and Co2+ were investigated and the sorption capacities towards Fe3+, Pb2+, Cu2+ and Cd2+ions were determined. The natural Bulgarian diatomites from Dragovishtitsa and Ignatievo were found as suitable low cost sorbents for the removal of milligram amounts of Fe3+, Pb2+, Cu2+ and Cd2+from contaminated waters. |
