构建OMMT/HP-MIL-101高性能黄曲霉毒素B1吸附剂
Construction of an OMMT/HP-MIL-101 adsorbent with high adsorption performance of AFB1
摘要
Abstract
Mycotoxin is a toxic secondary metabolite and is widely detected in animal feed.Among them,aflatoxin B1(AFB1)is the most noxious and common mycotoxin,and has caused serious biochemical and structural alterations in many organs mainly because their mutagenicity,teratogenicity and carcinogenicity.Therefore,it is an urgent to construct the high performance adsorbent for AFB1.Herein,we prepared the OMMT/HP-MIL-101 adsorbent using step-by-step modification.Firstly,the MMT was modified with cetyltrimethyl ammonium bromide(CTAB)to get OMMT.Compared with MMT,the interlayer spacing becomes bigger and exposes more adsorption sites,which can enhance the interaction between AFB1 and OMMT.Secondly,the OMMT was combined with MIL-101 with high specific surface area to form OMMT/MIL-101.The OMMT/MIL-101 exhibits the high specific surface area,which can provide the wide adsorption space for AFB1.Finally,the OMMT/HP-MIL-101 was fabricated by the treatment of methanol solvent at high temperature to obtain OMMT/HP-MIL-101.OMMT/HP-MIL-101 has higher specific surface area(1 147.71 m2/g),rich pore structure(micropore,mesopore and macropore),exposed more adsorption sites leading to the high adsorption capacity for AFB1(17.35µg/mg).In addition,the Freundlich isotherm is found to fit well in defining the adsorption performance of AFB1 on OMMT/HP-MIL-101,indicating a multi-layer adsorption process.This work displays that OMMT/HP-MIL-101 can serve as the powerful candidate for the adsorption of AFB1,and provides a theoretical basis for the construction of new porous adsorbents for AFB1.关键词
