Abstract
The biosorption of copper(II), nickel(II) and chromium(VI)
from aqueous solutions on dried (Chlorella vulgaris, Scenedesmus obliquus and Synechocystis sp.)
algae were tested under laboratory conditions as a function of pH, initial metal ion and biomass
concentrations. Optimum adsorption pH values of copper(II), nickel(II) and chromium(VI) were
determined as 5.0, 4.5 and 2.0. respectively, for all three algae. At the optimal conditions,
metal ion uptake increased with initial metal ion concentration up to 250 mg l(-1). Experimental
results also showed the influence of the alga concentration on the metal uptake for all the
species. Both the Freundlich and Langmuir adsorption models were suitable for describing the
short-term biosorption of copper(IT), nickel(II) and chromium(VI) by all the algal species. (C)
