Physical adsorbents for detoxification are widely used in vegetable oil industry. So far, the high-efficiency and low-cost adsorbents have not been well explored. Here, a hierarchical fungal mycelia@graphene oxide@FeO (FM@GO@FeO) was fabricated as an efficient adsorbent for simultaneous removal of aflatoxin B (AFB) and zearalenone (ZEN). The morphological, functional and structural characteristics of the prepared adsorbents were systematic investigated. Batch adsorption experiments in both single and binary systems were conducted, and the adsorption behaviours and mechanism were explored. The results indicated that the adsorption process occurred spontaneously and the mycotoxin adsorption could be described as physisorption through hydrogen bonding, π-π stacking, electrostatic and hydrophobic interactions. Due to good biological safety, magnetic manipulability, scalability, recyclability and easy regeneration, FM@GO@FeO performance is suitable for application as a detoxification adsorbent in vegetable oil industry. Our study addresses a novel green strategy for removing multiple mycotoxins by integrating the toxigenic isolates with advanced nanomaterials.
用于解毒的物理吸附剂在植物油工业中得到了广泛的应用。到目前为止，尚未很好地探索出高效且低成本的吸附剂。在这里，制备了一种分级真菌菌丝体/氧化石墨烯/FeO（FM@GO@FeO）作为一种有效的吸附剂，用于同时去除黄曲霉毒素 B（AFB）和玉米赤霉烯酮（ZEN）。系统地研究了制备的吸附剂的形态、功能和结构特征。在单一和二元体系中进行了批量吸附实验，探讨了吸附行为和机制。结果表明，吸附过程是自发发生的，真菌毒素的吸附可以通过氢键、π-π 堆积、静电和疏水相互作用来描述为物理吸附。由于具有良好的生物安全性、磁性可操作性、可扩展性、可回收性和易于再生性，FM@GO@FeO 的性能适合用作植物油工业中的解毒吸附剂。我们的研究通过将产毒分离物与先进的纳米材料结合，为去除多种真菌毒素提供了一种新的绿色策略。
