Hexavalent chromium is one of the major pollutants released from the tanneries that have a direct effect on man and animals. In this study, seaweeds such as Centeroceras clavulatum, Enteromorpha flexuosa, Grateloupia lithophila, Enteromorpha intestinalis, and Ulva lactuca, were collected from Covelong, Chennai. Sargassum sp., Amphiroa sp., Ulva sp., and Hypnea sp. were collected from Kanyakumari and Chaetomorpha antennina was collected from Puducherry. Different solvents such as methanol, ethanol, water, benzene and chloroform were used for extraction. Then these extracts were used to treat tannery effluent. The reduction in hexavalent chromium was analysed and correlated with phytochemicals of algal extracts. Results revealed that Cr(VI) concentration was highly reduced by benzene extract of Hypnea sp. (95%).Keywords

Heavy metals are toxic to the living bodies even though present in trace amounts. In this study, we have developed a simple approach for the biosynthesis of iron oxide nanoparticles (Fe3O4-NPs) using Trigonella foenum-graecum leaf extract and used it for possible removal of lead from aqueous solution and wastewater. SPR peak at 248 nm confirms the bioreduction and formation of Fe3O4-NPs. The shape and size of the nanoparticles were evaluated by SEM equipped with EDX, TEM, XRD. The particles were found crystalline and roughly spherical in shape with an average size range of 51.6- 215.7 nm. The possible biomolecules participated in the biosynthetic reaction which was confirmed by FTIR spectrum. These nanostructured particles were used for batch adsorption study for the removal of lead ions. The effects of various physical and chemical parameters like pH, contact time, adsorbent dosage and initial concentrations on the removal of heavy metals were studied on removal efficiency. The maximum lead(II) ions removal uptake was found 93±0.13% at pH 6.0 with 0.4g of these nanoparticles within 60 min of contact time. Desorption studies indicated that the regenerated nanoparticles retained its original metal adsorption efficiency. Results showed that these regenerable iron oxide nanoparticles can be used as nano-adsorbent for removal of heavy metals from environmental waste due to its high metal uptake capacity.Keywords
