NOVELTY - Preparing modified graphene oxide composite aerogel organic adsorbent of cyclodextrin involves stirring and slowly adding 10-12 pts. wt. cyclodextrin while stirring in 370-400 pts. wt. graphene oxide dispersion liquid, 8-10 pts. wt. sodium alginate and 8-10 pts. wt. starch, heating to 80-90 degrees C, ultrasonically processing for 2-3 hours to obtain the cyclodextrin modified graphene oxide intercalation composite hydrosol. The modified graphene oxide intercalation composite hydrosol is maintained at 60-70 degrees C, while stirring, added 6-8 pts. wt. eight arm polyethylene glycol carboxyl and 4-6 pts. wt. polyethylene imine, continuously stirred to form uniform graphene oxide hydrosol after finishing adding, then stopped stirring and heating to 90-95 degrees C and kept the temperature for 3-4 hours, cooled to obtain the cyclodextrin modified graphene oxide composite hydrogel. USE - Method for preparing modified graphene oxide composite aerogel organic adsorbent of cyclodextrin. ADVANTAGE - The method enables to prepare modified graphene oxide composite aerogel organic adsorbent of cyclodextrin has fast adsorption rate, the adsorption amount is large, organic absorption removing rate is more than 99 wt.%, is convenient to recycle and has the advantages of green and environment-friendly. DETAILED DESCRIPTION - Preparing modified graphene oxide composite aerogel organic adsorbent of cyclodextrin involves stirring and slowly adding 10-12 pts. wt. cyclodextrin while stirring in 370-400 pts. wt. graphene oxide dispersion liquid, 8-10 pts. wt. sodium alginate and 8-10 pts. wt. starch, heating to 80-90 degrees C, ultrasonically processing for 2-3 hours to obtain the cyclodextrin modified graphene oxide intercalation composite hydrosol. The modified graphene oxide intercalation composite hydrosol is maintained at 60-70 degrees C, while stirring, added 6-8 pts. wt. eight arm polyethylene glycol carboxyl and 4-6 pts. wt. polyethylene imine, continuously stirred to form uniform graphene oxide hydrosol after finishing adding, then stopped stirring and heating to 90-95 degrees C and kept the temperature for 3-4 hours, cooled to obtain the cyclodextrin modified graphene oxide composite hydrogel. The modified graphene oxide composite hydrogel is frozen and then and dried for 24-26 hours to obtain the cyclodextrin modified graphene oxide composite aerogel. The cyclodextrin modified graphene oxide composite aerogel is dipped in the cyclodextrin and graphene oxide layer mixed solution for 20-30 minutes, after draining at 115-135 degrees C for 2-3 hours for high temperature activation treatment, then cooled to obtain the cyclodextrin modified graphene oxide composite aerogel dye adsorbent.
