Efficient reduction of GO was performed, using cellular extracts of three algal strains. The rGO were characterized by SEM, TEM, UV-Visible spectroscopy, XRD, FTIR, Raman spectroscopy, Zeta potential and redox potentials. The rGO were then used as decontaminating agents for heavy metals (Cu and Pb), in waste water. GO reduced via JSC-1 have removed up to 93% Cu and 82% Pb (adsorption capacity of 93 mg g(-1) and 82 mg g(-1), respectively), by 211-9a have removed 74% (74 mg g(-1)) Cu and 89% (89 mg g(-1)) Pb, while by 211-11n have adsorbed 91% (91 mg g(-1)) Cu and 95% Pb (95 mg g(-1)), within 30 min.
