“…The antifouling behavior of metal-chelating materials is another important parameter to consider to evaluate their potential for water purification applications. The adsorption of organic matter on the surface of composites indeed reduces their metal ion-binding capacities and hence their applicability in water resources for prolonged periods of time [1,2,3,4,5,6,7]. We evaluated the adsorption of bovine serum albumin (BSA) (one of the most abundant proteins, which is well known for its high absorption behavior) on the surface of the polymeric composite.…”

“…Iron is one of the most common heavy metals in the Earth’s crust, which is required for normal physiological functions of the human body, in trace amounts. However, the presence of high concentrations of iron in ground water due to natural resources or human activity and the continuous exposure of high iron content to humans is associated with elevated health risks, including organ damage, heart diseases, and ophthalmic disorders [1,2,3,4,5,6,7]. The soluble form of iron (Fe 2+ ) is associated with an unpleasant taste, discoloration, turbidity, and microbial growth in water resources, and its removal from drinking water is the most cumbersome task [1,2,3,4,5,6,7].…”

The exponential increase in heavy metal usage for industrial applications has led to the limited supply of clean water for human needs. Iron is one of the examples of heavy metals, which is responsible for an unpleasant taste of water and its discoloration, and is also associated with elevated health risks if it persists in drinking water for a prolonged period of time. The adsorption of a soluble form of iron (Fe2+) from water resources is generally accomplished in the presence of natural or synthetic polymers or nanoparticles, followed by their filtration from treated water. The self-assembly of these colloidal carriers into macroarchitectures can help in achieving the facile removal of metal-chelated materials from treated water and hence can reduce the cost and improve the efficiency of the water purification process. In this study, we aim to develop a facile one-pot strategy for the synthesis of polymeric composites with embedded nanocrystalline cellulose (NCC) for the chelation of iron(II) from contaminated water. The synthesis of the polymeric composites with embedded nanoparticles was achieved by the facile coating of ionic monomers on the surface of NCC, followed by their polymerization, crosslinking, and self-assembly in the form of three-dimensional architectures at room temperature. The composites prepared were analyzed for their physiochemical properties, antifouling properties, and for their iron(II)-chelation efficacies in vitro. The results indicate that the embedded-NCC polymeric composites have antifouling properties and exhibit superior iron(II)-chelation properties at both acidic and basic conditions.
