Fixed Bed Column Filled with Rice Husk for the Removal of Cu (II) from Aqueous Solution
The performance of low-cost adsorbent such as rice husk fixed bed column in removing copper from aqueous solution were studied in this work. Different column design parameters like bed height, flow rate and initial concentration were calculated. It was found that at 10 mg/L concentration of Cu (Ⅱ) and at flow rate 5 mL/min with different bed depths such as 9, 12 and 15 cm, the breakthrough time increases from 150 to 260 min; the breakthrough time increases from 125 to 780 min with decreasing of flow rate from 15 to 5 mL/min and decreased from 260 to 50 min when initial concentration increased from 7 to 50 mg/L.
