This paper provides information on biosorption of Cd2+ by the cyanobacterium Aulosira fertilissima. Over all pattern of Cd2+ sorption rate seems to be dependent on the level of Cd2+ present in the external medium and length of exposure to metal. Cd2+ sorption was rapid during first five minutes thereafter the process slowed down and finally reached to saturation. A growth promoting pH (8.0) resulted more Cd2+ uptake than pH 6.0 and 10.0.

Abstract


This paper provides information on biosorption of Cd2+ by the cyanobacterium Aulosira fertilissima. Over all pattern of Cd2+ sorption rate seems to be dependent on the level of Cd2+ present in the external medium and length of exposure to metal. Cd2+ sorption was rapid during first five minutes thereafter the process slowed down and finally reached to saturation. A growth promoting pH (8.0) resulted more Cd2+ uptake than pH 6.0 and 10.0.
