Lead Removal from Contaminated Water Using Seaweed-Iron Oxide Nanoparticles Composite
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 Pb 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.. The results showed that all sorbents under investigation were successful for Pb 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 Pb 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.
