▎ 摘　　要

NOVELTY - Preparing regenerated bacterial cellulose composite aerogel adsorption material comprises (a) adding the bacterial cellulose powder to the mixed solution of sodium hydroxide, urea and water, pre-cooling at -12 to-20 degrees C for 30-60 minutes, stirring for 10-30 minutes to obtain a transparent bacterial cellulose solution and (b) adding the polyvinyl alcohol into the bacterial cellulose solution, stirring, dissolving, adding graphene oxide and attapulgite, dispersing uniformly, ultrasonically removing bubbles, casting the mixed solution into 12-hole culture plate, freezing and thawing to form columnar composite hydrogel, washing the hydrogel with distilled water to pH of 7.0 and freeze-drying to obtain the regenerated bacterial cellulose composite aerogel adsorption material bacterial cellulose / polyvinyl alcohol / graphene oxide/attapulgite. USE - The regenerated bacterial cellulose composite aerogel adsorption material is useful in absorbing dye and absorbing heavy metal ions, preferably copper ions and lead ions (claimed). ADVANTAGE - The adsorption material has low preparation cost, good acid-base stability and thermal stability, has good adsorption capacity for Congo red, methylene blue dyes and copper ions and lead ions heavy metal ions; has high regeneration rate after repeated use and used in industrial wastewater purification treatment.
