▎ 摘　　要

NOVELTY - Sodium alginate-hydrotalcite-graphene gel ball comprises sodium alginate gel sphere, and hydrotalcite and graphene embedded in the sodium alginate gel sphere. USE - The sodium alginate-hydrotalcite-graphene gel sphere is useful removing organic pollutants including p-nitrophenol (PNP) and p-aminophenol (PAP) in water (claimed). ADVANTAGE - The sodium alginate-hydrotalcite-graphene gel sphere can improves the mechanical strength and toughness of the gel ball, and the functional group can react with organic pollutant p-aminophenol in the adsorbent of also increases, and thus the removal rate removal rate to be high the p-aminophenol ratio of sodium alginate gel sphere. The method has simple steps, suitable operation and strong practicability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of the sodium alginate-hydrotalcite-graphene gel sphere comprising ultrasonically dispersing the oxidized graphene aqueous solution, sodium alginate, hydrotalcite to mix uniformly to form mixed liquid of sodium alginate-hydrotalcite-graphene, then dropping the mixed liquid into calcium chloride solution, and solidifying to obtain the sodium alginate-hydrotalcite-graphene gel sphere; #sodium alginate-hydrotalcite-graphene gel sphere is prepared by above mentioned method; and #removing organic pollutants including p-nitrophenol (PNP) and p-aminophenol (PAP) in water comprising adding the sodium alginate-hydrotalcite-graphene gel sphere into the water containing organic pollutants including p-nitrophenol (PNP) and p-aminophenol (PAP), oscillating and absorbing to obtain the product.
