改性活性炭构建菌载体及其吸附玉米中黄曲霉毒素B1 的工艺研究Construction of bacterial carrier by modified activated carbon and its adsorption of AFB1 from maize

旨在为生物处理黄曲霉毒素污染的粮食饲料提供技术支持，以活性炭（SH）为原料进行改性制备磁性活性炭（CSH），选用能高效降解黄曲霉毒素B1（AFB1）的芽孢杆菌属菌株WTX1与CSH载体共培养构建磁性菌载体（FCSH），脱除受污染玉米中的AFB1，对CSH进行BET比表面积、氮吸附-脱附等温线及其对AFB1的等温吸附曲线分析，考察FCSH构建条件和FCSH吸附条件对AFB1脱除效果的影响，并利用傅里叶变换红外光谱（FTIR）和扫描电镜对吸附AFB1前后的FCSH进行表征。结果表明：CSH为大孔结构，其对AFB1的等温吸附符合Freundlich方程；在固定化时间16 h、固定化转速和吸附转速16...
