| Summary: | Spent grated coconut treated with sulphuric acid had been evaluated as a potential
low cost biosorbent. It had been used for the removal of copper(II) from the
aqueous solution using fixed-bed column mode. The parameters were fixed for
this study using; 50 mg/L influent concentration, 10 mL/min flow rate, 1.5 cm
bed-depth and pH 5. The adsorption capacity obtained from breakthrough curve
was 35.785 mg/g. The breakthrough time, tb at 71.57 min, while t50% at 118.36
min and exhaustion time, texh at 211.23 min for 2050 mL. The R2 of Thomas
model was 0.885 and qo was 66.50 mg/g while R2 of Yoon-Nelson model was
0.879 and qoYN was 66.75 mg/g. |
