Abstract

The key objective of present study was to find out a novel and innovative strategy to tackle the problem of cyanide and metal-cyanide pollution. Studies were performed to test the feasibility of treating aqueous waste containing free cyanide (CN-) and copper-cyanide {Tetracyanocuprate - TCC, [Cu(CN)4]-2} using microalgae Scenedesmus sp. that was isolated by enrichment culture technique under alkaline conditions. Results revealed that microalgae Scenedesmus sp. was capable of detoxifying cyanide and TCC (10-25 mg/l as CN-) with an efficiency of >99% under aerated, static and illuminated conditions within a period of 48-96 h.
Process parameters like pH (7-11), temperature (20-45°C), initial cell density (103-106 cells/ml) and varying concentration of cyanide and TCC (5-50 mg/l as CN-) were optimized. Of the total copper ions released during biodegradation of TCC, 37% was adsorbed on the cells, while 67% was accumulated by Scenedesmus cells.
