Preparation method of electrochemical sensor modified electrode for detecting degradation product glucose of cotton and linen cultural relics

The invention relates to the field of textile cultural relic detection, and discloses a preparation method of an electrochemical sensor modified electrode for detecting degradation product glucose of cotton and linen cultural relics. A C-SiO2 adsorption material is prepared from a carbon-containing substance and silicon tetrachloride, then a porphyrin copper complex is prepared, and a C-SiO2 adsorption material diluent and a porphyrin copper complex suspension are dispensed on the surface of an electrode through a layer-by-layer assembly method, so that a stable modified electrode is formed, and the electrode has excellent detection capability on the cotton and linen degradation product glucose. 本发明涉及纺织品文物检测领域，公开了一种用于检测棉麻文物降解产物葡萄糖的电化学传感器修饰电极的制备方法。本发明将含碳物质和四氯化硅制备成C-SiO2吸附材料，再制备出卟啉铜配合物，通过层层组装的方法将C-SiO2吸附材料稀释液和卟啉铜配合物悬浮液滴涂在电极表面，从而形成稳定的修饰电极，该电极对棉麻降解产物葡萄糖具有出色的检测能力。
