Abstract

Silicate-based composite materials have great potential as adsorbents in the field of mycotoxin removal. In this study, a porous graphitic carbon coated attapulgite (APT/C-ZnCl₂) composite material was successfully prepared using an in-situ thermal reduction method with glucose as the carbon source. This composite material exhibited excellent adsorption performance towards aflatoxin B1, zearalenone, and deoxynivalenol. Experimental results indicated that the adsorption rates of the composite material towards the three mycotoxins reached 93.52 %, 90.58 %, and 92.31 %, respectively, with saturated adsorption capacity of 20.17 mg/g, 82.67 mg/g, and 0.69 mg/g, respectively. The interaction between APT/C-ZnCl₂ material and aflatoxin B1 was mainly attributed to H-bonding interaction, while its interactions with zearalenone and deoxynivalenol were primarily governed by hydrophobic and π-π interactions. Overall, porous silicate-based APT/C-ZnCl₂ adsorbent has the characteristics of ultra-high adsorption capacity, low cost, and adsorption ability for different types of fungal toxins, meeting the requirements of efficient and economical removal of mycotoxins.

熔融盐活化诱导多孔石墨碳/凹凸棒土复合材料作为多种真菌毒素的优良吸附剂

硅酸盐基复合材料作为吸附剂在霉菌毒素脱除领域具有广阔的应用前景。本研究以葡萄糖为碳源，采用原位热还原法制备了多孔石墨碳包覆凹凸棒土（APT/C-ZnCl2）复合材料。该复合材料对黄曲霉毒素B1、玉米赤霉烯酮和脱氧雪腐烯醇具有良好的吸附性能。实验结果表明，复合材料对3种真菌毒素的吸附率分别达到93.52%、90.58%和92.31%，饱和吸附量分别为20.17 mg/g、82.67 mg/g和0.69 mg/g。APT/C-ZnCl2材料与黄曲霉毒素B1的相互作用主要是h键相互作用，而与玉米赤霉烯酮和脱氧镰刀菌烯醇的相互作用主要是疏水和π-π相互作用。综上所述，多孔硅酸盐基APT/C-ZnCl2吸附剂具有超高吸附容量、低成本、对不同类型真菌毒素均有吸附能力的特点，满足高效、经济去除真菌毒素的要求。
