摘要:

Deoxynivalenol (DON), which is known as one of the most harmful mycotoxins, has contaminated food and feed and attracted concerns worldwide. However, the effective adsorptive removal of DON to ensure food safety still is a challenge, which is ascribed to the poor planarity and larger steric hindrance of DON molecules. Here, a new Zr(IV)-based metal-organic framework, entitled BUT-16 with one-dimensional channels and N-atom-decorated pore surface, is designed, prepared, and utilized for the adsorptive removal of DON. It exhibits excellent adsorption ability with an adsorption capacity of 46 mg/g higher than all reported adsorbents until now and a rapid adsorption rate of 0.031 g mg(-1) min(-1). DFT calculation and X-ray photoelectron spectroscopy results of the guest-loaded phase suggest that the record-breaking adsorption could be due to the cooperation of hydrogen bonding and Zr center dot center dot center dot O interaction between DON molecules and BUT-16 host. Most importantly, BUT-16 can effectively adsorb and remove DON in the simulated gastric fluid, but DON adsorbed on BUT-16 is hardly desorbed in the simulated intestinal fluid. The results demonstrate that BUT-16 has great promising application for the control of DON in foods and feeds.
