Background: Pay attention to phenol is important because of its sustainability in the environment and creating health problems. Due to the high solubility of phenol in water, it must be removed in order to prevent contamination of water resources and the environment. The aim of this study is to assess the efficacy of M. azedarach seed ash for removal of phenol from aqueous solutions.
Methods: In this experimental study, M. azedarach seed ash was used for removal of phenol from aqueous solutions. In this study, the effect of the factors affecting adsorption was studied, including adsorbent dosage, initial phenol concentration, contact time, pH and temperature. Data obtained from the tests were analyzed using Excel software. Langmuir and Freundlich isotherm models were employed to verify compliance of absorption process from the isotherm models.
Results: Experimental results indicated that the efficacy of M. azedarach seed ash for removal of phenol had a direct relationship with increasing adsorbent dosage, temperature and contact time, as well as an inverse relationship with increasing pH and initial phenol concentration. According to the correlation coefficient of adsorption isotherm models, adsorption of phenol followed the Freundlich model.
Conclusions: The results of the present study showed that M. azedarach seed ash is effective for removal of phenol from aqueous solution. Given the ability to grow of M. azedarach tree in hot and dry climates, it can be used as an inexpensive and accessible adsorbent.
