INVESTIGATION OF DESMODESMUS ARMATUS FOR LEAD (Pb+2) AND NICKEL (Ni+2) REMOVAL CAPACITY FROM METAL POLLUTED WATER

This research was carried out in order to investigate the lead and nickel removal of Desmodesmus armatus. D.armatus was applicated three doses (0.025 mg L-1, 0.21 mg L-1, 0.25 mg L-1) lead and three doses (0.02 mg L-1, 0.05 mg L-1, 0.3 mg L-1) nickel. As a result of the experiment, it was determined that the highest absorbance was 0.023 +/- 0.0 mgL(-1) on the 13th day of lead application with 0.025 mgL(-1) dose. In this study has been found that D.armatus removes about 80% of the lead in the water. The live cells of D.armatus were able to remove about 50% of the nickel in the water but nickel retained back to the water by die cell of D.armatus. As a result of in this research, D.armatus was found to be effective in lead elimination, but nickel removal was determined to be possible only with living cells.
