Metal–organic framework (MOF)-embedded magnetic polysaccharide hydrogel beads for rapid and selective adsorption of malachite green and crystal violet

, respectively, demonstrating outstanding dye removal ability. These magnetic microspheres also enabled rapid solid-liquid separation under an external magnetic field, supporting convenient operation and reusability. Overall, these composite microspheres represent a promising adsorbent for efficient removal of organic dye contaminants from aquatic product matrices, with strong potential for food safety applications.
