The presence of phenol and its derivatives in water and wastewater are of major concern because of their toxicity and threat to human life and environment. In this study, ostrich feather has been used as a new adsorbent in removal of phenol in different doses of 0.2, 0.3, 0.5, 0.7, 1 and 1.5 g and the effects of changing contact time, pH, adsorbent dose and temperature has been determined. Then, the adsorption data were described with Langmuir and Freundlich adsorption isotherms and Excel software for analyzing the data was used. The results obtained revealed that by increasing the dosage of the sorbent from 0.2 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 (70%) from solution. The adsorption equilibrium was well represented by the Freundlich and Langmuir adsorption isotherms. The results showed that the ostrich feathers, a solid waste produced in poultry processing plant, can be used as an effective biosorbent for removal phenol in aaqueous solution.
