[0034] Modified silica gel Synthesized by:
[0035] Add 20 g of silica gel into concentrated hydrochloric acid, heat to reflux for 6 hours, wash with deionized water until neutral, and dry at 180° C. for 16 hours to obtain activated silica gel. Add 8g of activated silica gel to 80mL of dry toluene solvent, slowly add 8mL of 3-chloropropyltriethoxysilane dropwise, under the protection of nitrogen, reflux for 12h, filter, and the product is washed with toluene, ethanol and ether several times Wash and dry in vacuum at 80°C for 6h. Add 6g of thiosemicarbazide into 100mL of ethanol, heat to dissolve, add 8g of the above product, reflux for 8h, filter, wash with ethanol and hot water several times, and vacuum dry at 80°C for 12h to obtain the target product.
