Background and purpose: Phenol is an organic pollutant that is found in industrial effluents and is very toxic to human and the environment. The purpose of this study was to use the ostrich feathers ash as a natural absorbent to remove phenol from aqueous solution.
Materials and methods: For this study, ostrich feather ash was used as a new adsorbent in removal of phenol at different doses (0.2, 0.3, 0.5, 0.7, 1, 1.5, 2 and 3 g). Çhanges following the effect of contact time, pH, adsorbent dose, temperature and initial phenol concentration have been recorded. Then, the adsorption data were described with Langmuir and Freundlich adsorption isotherms and Ëxcel software was used for data analysis.
Results: There is a dose-dependent relationship between phend adsorption by absorbent at doses ranging from 0.2-2 g. The adsorption of phenol decreases following an increase in the pH of the solution. Âlso, it is observed that the contact time significantly affects the rate of phenol adsorption (77%) from solution.
Çonclusion: Generally, the studied adsorbent was applied successfully for treating industrial water samples and aqueous solution.
