Paper Title:
Study on Heavy Metal Adsorption in Coastal Sediment of the Yellow River Estuary
  Abstract

We took the surface sediments of the Yellow River as the objects to study the adsorption characteristics of Cu and Pb in coastal sediments. The results indicated that: the smaller the granularity is, the bigger the saturated adsorption capacity is; The adsorption equilibrium time of Cu2+, Pb2+ is different, but all can achieve adsorption equilibrium in 1.5h; The adsorption capacity increases gradually along with pH, which increases rapidly for Cu2+, but increaseing slowly for Pb2+. The adsorption capacity of Cu2+ assumes a linear relation with initial concentration of absorbent basically; which increases rapidly under lower initial concentration of absorbent for Pb2+, but then becomes lower. The adsorption capacity of Cu2+, Pb2+ increases along with the equilibrium concentration, which increases rapidly for Cu2+, but increases rapidly for Pb2+ when the equilibrium concentration is relatively lower, then tends to slow down along with the concentration.
