A magnetic-cored dendrimer (MCD) is a nano-sized, hyperbranched polymeric adsorbent composed of a magnetic core, branch, and functional end groups. Incorporation of a magnetic core with high specific surface area enables the recovery and reusability of the dendrimers by exacting a magnetic force to recover the dendrimers. The structure of dendrimers can be customizable by tailoring the number of branches and functional end groups generated. With every increase in generation, the number of functional end groups within the dendrimer will be doubled and the synthesis can be repeated several times to achieve the optimal number of generations for the application.
The technology offered presents a solution to synthesize magnetic-cored dendrimers for environmental decontamination. Various functional groups such as amine, carboxyl, thiol, methyl, and hydroxyl groups, can be easily attached as end-groups to remove organic and inorganic contaminants. Contaminants are removed via adsorption or electrostatic interactions with the functional end groups.
MCDs produced from the technology consists of:
Other attributes of MCD include:
MCDs produced can be applied to water bodies for organic and inorganic contaminant removal and for environmental remediation activities in various industries such as chemicals, textiles, and pharmaceuticals. Depending on the type of functional end groups, various contaminants can be treated by means of MCD.
Applications using MCD include (but not limited to):
