The capacities of montmorillonite K10 (K10), aluminum pillared K10 (Al-K10), and iron pillared K10 (Fe-K10) to eliminate zearalenone (ZEN) from synthetic media and the aqueous part of canned corn were studied. Original clay and pillared clays were characterized in terms of X-ray powder diffraction analysis and N(2) adsorption-desorption isotherms. The maximum amounts of adsorption of ZEN by K10, Al-K10, and Fe-K10 at 25°C and pH 7 were 0.202, 1.305, and 1.028 mg/g and 0.264, 0.096, and 0.255 mg/g, calculated from Langmuir and Freundlich isotherms, respectively. The adsorption of ZEN was also studied as a function of adsorbent amount (1 to 30 mg), ZEN concentration (2 to 20 mg/liter), pH of solution (pH 4 to 10), and contact time. Pillared clays could be an excellent alternative for removing ZEN in contaminated food samples and are potentially low-cost adsorbents with a promising future as an alternative to more costly materials.
研究了蒙脱石 K10（K10）、铝柱撑蒙脱石 K10（Al-K10）和铁柱撑蒙脱石 K10（Fe-K10）从合成介质和罐装玉米水相中去除玉米赤霉烯酮（ZEN）的能力。原土和柱撑土分别通过 X 射线粉末衍射分析和 N2 吸附-解吸等温线进行了表征。在 25°C 和 pH 7 下，K10、Al-K10 和 Fe-K10 对 ZEN 的最大吸附量分别为 0.202、1.305 和 1.028 mg/g 和 0.264、0.096 和 0.255 mg/g，分别根据朗缪尔和弗伦德利希等温线计算得出。还研究了 ZEN 的吸附作为吸附剂用量（1 至 30 mg）、ZEN 浓度（2 至 20 毫克/升）、溶液 pH 值（pH 4 至 10）和接触时间的函数。柱撑粘土可能是去除污染食品样品中 ZEN 的极好替代品，并且作为更昂贵材料的替代品具有潜在的低成本吸附剂，具有广阔的前景。
