| Summary: |
This project paper presents the results of experiment carried out on sorption of Cr
(III) ions from chromium solution by eggshells as a low cost sorbent. The eggshell in
a powdered form is a potentially beneficial option for the removal of toxic chromium
from industrial wastewater. The principal component of the shell is calcium
carbonate which comprises more than 90% of the carbon material. Crushed eggshells
possess relatively high sorption capacity, when comparing with other sorbents. The
effect of process parameters: contact time, sorbent dosage, pH, and temperature,
initial concentration of Cr (III) ions on the process was studied. Sample eggshells
collected washed thoroughly using sodium hydroxide solution and deionized water.
The eggshells were then dried at 110°C in an oven and crushed accordingly and later
stored in quick-fit glass bottles for further use. |
