Characteristics of Cr (VI) Adsorption in Aqueous Solution by Wheat Straw

Abstract:

The adsorption process of Cr (VI) in aqueous solution on activated carbon prepared by wheat straw was investigated to study the effect factors on adsorption properties. adsorption mechanism was discussed. The results showed that the adsorption performance was influenced by dosage, initial concentration and adsorption time. Adsorption reached equilibrium after 100 min at temperature 25°C. The highest removal efficiency can reach 94%. The results indicated that activated carbon as adsorbent can effectively deal with waste water containing (VI).
