Magnetic hybrid imprinted polymers with three-templates modified by DESs for the rapid purification of monosaccharide from <i>seaweed</i> LiGuizhen RowKyung Ho 2017 <p>Fe<sub>3</sub>O<sub>4</sub>@hybrid-molecular-imprinted polymers (Fe<sub>3</sub>O<sub>4</sub>@HMIPs) with three monosaccharide templates (D-(+)-galactose, L-(−)-fucose, and D-(+)-mannose), and hybrid materials were modified by deep eutectic solvents (DESs). The materials obtained were combined with solid-phase extraction (SPE) to purify of D-(+)-galactose, L-(−)-fucose, and D-(+)-mannose from <i>seaweed,</i> and the SPE procedure was optimized further. Compared to Fe<sub>3</sub>O<sub>4</sub>@HMIPs, DESs-Fe<sub>3</sub>O<sub>4</sub>@HMIPs were developed to achieve stronger recognition and higher recoveries of D-(+)-galactose, L-(−)-fucose, and D-(+)-mannose from <i>seaweed</i>. The optimal practical recoveries of the three monosaccharides, D-(+)-galactose, L-(−)-fucose, and D-(+)-mannose, purified by DESs-4-Fe<sub>3</sub>O<sub>4</sub>@HMIPs from <i>seaweed</i> were 90.12, 92.82, and 91.94%, respectively. When acetone was used as the washing solution, the actual amounts extracted were 6.87, 4.17, and 5.29 mg · g<sup>−1</sup>, respectively.</p>
