AbstractThe aim of the present work is to study the removal of copper ion presents in
industrial waste water using the local sawdust.
Adsorption column was utilized in the removal process at constant temperature.
The effect of the concentration of copper ion in the range (100-500) mg/L was
studied. Increasing the inlet ion concentration increases the slope of the breakthrough
curve. The effect of bed height in the range of (10-30) cm on copper ion
adsorption from wastewater was studied. The increase in bed height increases the
break point values. The effect of flow rate in the range (0.5-1.5) cm3/sec on copper
ion adsorption also was studied. Increasing the flow rate decreases the breakthrough
time. The best operating conditions in this work for copper ion adsorption
are 100 mg/L of feed, 30 cm bed height and 0.5 cm3/sec feed flow rate. It was
found that the equilibrium relation agrees with Langmuir & Freundlich equations.
Finally accumulation adsorption of copper ion at different operating conditions
