| Abstract | ||||
| Water sacristy is one of the most global concerns in the last decades, which can be solved by reusing wastewater. Lead, as a potentially toxic element, is one of the most dangerous potentially toxic elements that have to be eliminated from contaminated water resources. Bio-sorbents, like macroalgae (seaweeds) have been recently investigated for removing toxic elements from water. It is hypothesized that mixing seaweeds with nanoparticles (e.g. iron oxide) might improve removal efficiency of Pb2+ ions. In this study seaweeds, iron oxide nanoparticles and their composite were used for lead removal from contaminated water with up to 50.0 mg L-1.. The results showed that all sorbents under investigation were successful for Pb2+ sorption, and the engineered composite was superior with removal efficiency of 91%. In addition, the engineered composite showed an ease of separation following sorption process using a magnet. Freundlich isotherm model was the best for describing the adsorption of Pb2+ onto the sorbents material under this investigation. This study is a step on the way to improve the separation of bio sorbents from aqueous solutions after the removal of contaminants. | ||||
