▎ 摘  要

NOVELTY - A heavy metal adsorbent is composite material of graphene-oligomerization 3-aminopropyl triethoxysilane which is obtained by hydrolyzing supernatant fluid containing graphite oxide and 3-aminopropyl triethoxysilane at 40-50 degrees C. USE - Heavy metal adsorbent (claimed). ADVANTAGE - The heavy metal adsorbent has excellent property in aspect of heavy metal wastewater treatment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of heavy metal adsorbent, which involves adding 3-aminopropyl triethoxysilane, graphite oxide and deionized water, stirring at room temperature, filtering, separating the flocculent, precipitating, centrifuging the resultant product, freezing and drying.
