中文摘要: 在室温条件下合成金属有机框架(metal-organic frameworks,MOF-5)材料,通过红外光谱、粉末衍射等技术对其结构进行表征;以苏丹红I 为目标物,考察了MOF-5的吸附性能,探究MOF-5作为富集材料用于食品中苏丹红检测的可行性。研究结果表明:室温条件下成功合成MOF-5材料;所制备的MOF-5材料对苏丹红I 具有优良的吸附性能,其最大吸附容量为20.7 mg/g,吸附在10 h 之内可以达到平衡;鉴于其优异的吸附性能,进一步考察其作为萃取材料用于鸭蛋中苏丹红I 检测的可行性。
Abstract:Metal-organic frameworks(MOF-5)material was synthesized at room temperature,and character ized by infrared spectroscopy,powder diffraction and thermogravimetric analyzer,etc.The adsorption property of MOF-5toward Sudan red I was investigated in detail.The feasibility of MOF-5as adsorption material for the detection of Sudan red I in foods was investigated.The results revealed that MOF-5material was successfully synthesized.The resulted in materials exhibited excellent adsorption property,where the maximum adsorption capacity was 20.7 mg/g and adsorption equilibrium was achieved within 10 h.Based on its excellent adsorption property,the detection of Sudan red I from duck eggs was realized.
