Adsorption of Copper (Ⅱ) from Solution by Wheat Husk in Batch Mode

摘要：

　　Wheat husk,an agriculture byproduct,was used to adsorb copper (Ⅱ) from aqueous solutions.Variables of the system,including contact time,pH,salt concentration,and equilibrium copper concentration,were adopted to study their effects on copper (Ⅱ) adsorption.The results showed that coexisted salt was not favor of adsorption and pH value near 5 was favor of adsorption.Adsorbent quantity of copper onto wheat husk increased with the equilibrium concentration increasing.The kinetic process can be predicted by Elovich model while the equilibrium data was fitted better by Freundlich model.
