AI Technical Summary
Existing technologies for removing arsenic from earthworm protein are costly, complex, and result in significant losses of the earthworm protein. Furthermore, existing methods may damage the protein structure.
A magnetic material Fe3O4-COOH@UiO-66-NH2 was prepared by specifically adsorbing arsenic and then rapidly separating it, avoiding the loss of the structure and content of earthworm protein. FeCl3·6H2O, sodium citrate, ethylene glycol and 2-aminoterephthalic acid were used as raw materials. Microwave treatment and vacuum drying technology were combined to shorten the synthesis time and improve the yield.
It achieves efficient removal of arsenic in a short time, avoids structural damage and content loss of earthworm protein, reduces production costs, and improves production efficiency and material yield.
