NOVELTY - Construction of a composite metal-organic framework of graphene oxide/copper(III) bis(benzene-1,3,5-tricarboxylate)/iron(II,III) oxide photocatalyst. USE - Used as construction of composite metal-organic framework of photocatalyst. ADVANTAGE - The photocatalyst: has tunable pore sizes and large; degrades aflatoxin B1 with an efficiency of 99% in the presence of UV light; has magnetic properties, hence that can be very easily recovered; decreases the activity by 99% to only 88% after 5 cycles of reuse; and utilizes copper(III) bis(benzene-1,3,5-tricarboxylate) that has high absorption capacity and photo-activity synergy, thus offering a quick, effective and green solution to aflatoxin B1 breakdown.
