▎ 摘　　要

NOVELTY - High-density amino polymer modified graphene oxide adsorbent comprises adsorbent is modified with dopamine and polyethyleneimine, and contains high amino density by method of secondary modification functionalized graphene nano composites. USE - The high-density amino polymer modified graphene oxide adsorbent is useful to adsorb heavy metal Cr(VI) (claimed). ADVANTAGE - The metghod is simple, natural and environment-friendly. The obtained adsorbent can effectively remove chromium (VI) in water, and has better adsorption effect to chromium (VI).
