Comparison efficiency of raw feather and Modified ostrich feathers by H2O2 for phenol removal from aqueous solutions

The removal of phenol by biosorbent has received increasing interest in recent years. In this study the potential of ostrich feathers was assessed for adsorption of phenol from aqueous solutions. In this research, feasibility of application ostrich feather and modified feather was studied at the laboratory scale using a synthetic phenol solution (1-50) mg/L and the impact of the important field parameters including pH, sorbents concentration, retention time and temperature were investigated. Then, the adsorption data were described with Langmuir and Freundlich adsorption isotherms and Excel software for analyzing the data was used. The result obtained revealed that by increasing the dosage of the sorbents from 0.2 g to 0.7 g the adsorption increases. The adsorption of phenol decreases by the increase of the pH value of the solution. Also, it is observed that the contact time significantly affect the rate of phenol adsorption (83% for raw feathers and 73% for modified feather) from solution. The Results showed that efficiency of raw feather process is more than of modified feather process for phenol removal. The results showed that the ostrich feathers as an economic material and disposal solid waste from poultry processing plants can be used as an effective biosorbent for phenol.
