Abstract
Short term uptake of cu, ed and Zn by the Cyanobacterium Aphanocapsa p ulchra (Kutz) Rabenh was studied under dark and light conditions. Upta ke of heavy metals amended with different combination of metals and ni trate was studied. Uptake of metals in immobilized cells showed 75-94% removal in a retention time of 5 min. Increasing the retention time i ncreased the removal percentage for Cd and Zn. The possibility of empl oying this organism for industrial effluent treatment is suggested. Zn interfered with Cd uptake and not the vice versa. All other heavy met al combinations showed no inhibitory effect on the uptake.
