Abstract

Background: The kinds of pollutants such as heavy metals, especially, can be removed from water and waste water by biological materials via BIOSORPTION. These heavy metals can be also recovered by adsorbents. The mentioned methods have more importance due to the advantages such as cheapness. Method: In this study marine red alga Gerasilaria sp. was used as an aquatic fern to remove Ni2+in the flow operation. Glass columns with an internal diameter of 2 Cm and 35 Cm in length were investigated as a packed column.Results: The adsorption process with influencing factors such as initial concentrations, pH, retention time (15, 30 and 45 min), and adsorbent dosage (2.5 and 3.5 g) in temperature home were considered. Synthetic solution of Ni (II) in distilled water was prepared using NiCl2.6H2O (97%) with initial concentrations 25, 40, 70 mg/L.Conclusion: The maximum uptake at pH=5 were obtained 83.01%, 80.69% and78.23% respectively. An atomic absorption spectrometer (GBC-932) was used for analyses of the artificial waste after exposure to alga. It was shown that the non-living Gerasilaria sp. adsorb according to Langmuier physical low and the kinetic studies was appeared that all of the used non-living alga samples adsorbed according to a second order model of kinetic
