Abstract:

Bio sorption potential of cyanobacteria in absorbing lead and chromium was carried out as an experimental study. The algae collected from the rice field are examined for the lead and chromium absorption potential. Visual changes, followed by disintegration of the cyanobacterial mat had gradually progressed with the increase in concentration of lead and chromium from 0 ppm to 150 ppm which indicates the metal absorption. The FT-IR spectra showed about 10 functional groups are involved in the future reactions of algae. The functional group dominant in lead treated cyanobacterial mat was OH and CO. The O-H Functional group, which shows isomerism of a ketone group C-O which has the highest intensity when it comes to binding and reaction process. The cyanobacteria mat has shown better absorption in Cr (VI) than Pb (IV). From the bio sorption study using the cyanobacterial mats showed promising results that would be efficient in reducing the heavy metal contamination in our ecosystem.
