Biological Treatment of some Essential Metals by Using Chlorella Vulgaris

Summary/Abstract: Heavy metal pollution is one of the most important environmental problems today. Essential elements are the elements that are used in metabolic activities by organisms in order to sustain their lives. Nonexistence of this elements causes imbalance of the homeostasis. Copper, zinc, cobalt, manganese and molybdenum are essential heavy metals that pose serious health hazards through entry into the food chain by anthropogenic pathways. This study aimed to determine the removal capacity for Cu (II), Co (II), Zn (II), Mo (VI) and Mn (II) heavy metals from 0,5; 1; 2,5; 5 ve 10 ppm concentration of aqueous solutions by using live C. vulgaris (Chlorophyta) microalgae. Experiments were performed using synthetic single-metal solutions of Cu, Co, Zn, Mo and Mn prepared from chemical reactants of analytical grade: CuSO4•5H2O, CoSO4•7H2O, ZnSO4•H2O, Na2MoO4.2H2O and MnCl2.4H2O, respectively. Based on the experimental data, the average adsorption capacities for Cu(II), Co(II), Zn(II), Mo(VI) and Mn(II) were 241.006, 238.120, 237.033, 223.396 and 54.899 mg/g by Chlorella cells, respectively. The obtained results showed that these biosorption systems using algal cells represent promising alternative for the removal of heavy metal ions from polluted aqueous environments.
