The use of local sawdust as an adsorbent for the removal of copper ion from wastewater using fixed bed adsorption

Abstract EN

The 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 and Freundlich equations.

Finally accumulation adsorption of copper ion at different operating conditions was calculated.
