Sorption of heavy metal ions by algae Spirogyra sp., obtained from
Lake Lesne in Pokrzywna, Poland, was investigated both under static
and dynamic conditions. Algae were separated from the substrate and
other mechanical impurities, and rinsed with demineralized water
(conductivity κ=0.5 μS/cm). Then, the initial concentrations of heavy
metals Mn, Cu, Zn and Cd in the algae were determined, using a
SOLAAR 969 atomic absorption spectrometer from UNICAM (prod.
Thermo Electron Corporation, USA).
