Abstract

Introduction: Lead is the major toxicant found in industrial effluent that can adversely
affect environment and human health. Conventional methods for the removal of this metal
from waste waters are often cost prohibitive. This study was conducted to investigate the
effect ostrich feathers modified by hydrogen peroxide on lead removal from waste water.
Methods: In this descriptive and practical study, ostrich feathers were used for removal of
lead from model solutions. Ostrich feathers were modified with hydrogen peroxide (30%
w/v) and distilled water for 18 hr. In this study, effect of pH (2-9), temperature (20-400C),
contact time (0.5-12 hr), sorbent dosage (0.3-1 gr) and initial concentration (1-15 mg/l) were
investigation in batch system. All the experiments were conducted in triplicate.
Experimental results were fitted to Langmuir and Freundlich isotherm models and Excel
software was used for data analysis.
Results: The results show that the maximum lead adsorption by modified feathers reached
within pH 5, contact time 8 hr, feather dosage 0.7 g and temperature 30◦C for concentration
range of 1-15 mg/L. Adsorption equilibrium data fit most satisfactorily with the Freundlich
and Langmuir isotherms.
Conclusion: According to the results, because of its inexpensive and availability, ostrich
feathers can be used as a suitable method to reduce the level of Lead from the aqueous
solutions in the contaminated places throughout the country.
