Due to the increasing use of the adsorption process for the removal of environmental pollutants, selecting a suitable material as an adsorbent has been a major concern of researchers in this field from the technical and economic aspects. This study aims at identifying the possibility of using Cumin Straw Ash (CSA) for removing phenol from aqueous solutions. Cumin Straw Ash was used as an adsorbent at a rate of 2.4, 8.15 and 25 mg/l in laboratory scale in a batch system and changes of phenol concentration, pH and contact time and the adsorption process abeyance from Freundlich and Langmuir equations was investigated. All experiments were performed according to Examination of Water and Wastewater Standard Methods. Besides, Excel software was used to analyze the data and Cumin Straw Ash is highly efficient in removing phenol and the absorbed phenol is reduced by increasing the pH value and removal efficiency is directly related with the increase of adsorbent. The best adsorption efficiency was obtained with adsorbent dosage (dose) of 0.1 g/100 ml, pH 7, phenol concentration 10 mg/l and the contact time of 75 min. Moreover, phenol adsorption process on Cumin Straw Ash obeys from Freundlich isotherm more than Langmuir isotherm. Low cost of cumin straw and the use of Cumin Straw Ash in phenol removal are recommended as an alternative or an option together with other treatment methods. © 2016, Taylor and Francis Inc.
