Sericin-based hydrogel and preparation method and application of carbonized product of sericin-based hydrogel

The invention discloses a sericin-based hydrogel and a preparation method and application of a carbonized product of the sericin-based hydrogel, and relates to the technical fields of biomass resource recycling, water pollution control and carbon adsorbent preparation. According to the preparation method of the sericin-based hydrogel and the carbonized product thereof, sericin protein in silk reeling wastewater is taken as a main raw material, sericin protein/carboxymethyl chitosan (SS/CMCS) composite hydrogel is prepared under 3V direct-current voltage by utilizing an electro-deposition technology, and then the sericin protein/carboxymethyl chitosan (SS/CMCS) composite hydrogel is prepared through a specific carbonization process to prepare the carbonized product of the sericin-based hydrogel and the carbonized product of the sericin-based hydrogel. According to the method, the SS/CMCS composite gel is prepared into a sericin-based carbon adsorbent (SC) with a three-dimensional pore structure, methylene blue
