Research on the Making of Activated Carbon from Disposable Chopsticks and its Adsorption Characteristics for Cr(VI)

Abstract:

The adsorption process of Cr (VI) in aqueous solution on activated carbon prepared by discarded disposable chopsticks was investigated to study the effect factors on adsorption properties. adsorption mechanism was discussed. The results showed that the adsorption performance was influenced by partical size, dosage, pH of medium, initial concentration and adsorption time. Adsorption reached equilibrium after 60min at temperature 25°C, pH=3, 80 mesh of adsorbent particle size. The highest removal efficiency can reach 92%. The results indicated that activated carbon as adsorbent can effectively deal with waste water containing (VI).
