fa بهداشت Health پژوهشي Original Article <div style="text-align: justify;">Background and purpose: Phenol is an aromatic hydrocarbon and one of the banzan derivatives which has a higher dissolution rate in water. Therefore, it must be removed for water pollution prevention. The aim of this study was to investigate the possibility of Pistaciamuticabio mass as an alternative adsorbent for phenol removal from aqueous solution.<br> Materials and Methods: The effect of various parameters including contact time (10-102 min), pH(2-8), adsorbent dosage (0.4-1.5g/L), phenol concentration (50-150mg/L) were investigated in this experimental-lab study. Also, the isotherm and kinetic investigations were performed for phenol adsorption process. The adsorption equilibriums were analyzed by Langmuir, Temkin, Freundlich and Harkins Jura isotherm models.<br> Results: It was found that the data fitted to Langmuir (R2=0.98) better than other isotherm models. Batch kinetic experiments showed that the adsorption followed Pseudo second-order kinetic model with correlation coefficients greater than 0.998.<br> Conclusion: It was revealed that P. mutica was not only an inexpensive absorbent, but also a quite effective factor in removal of phenol from water and wastewater.</div> Adsorption, Aqueous solution, Pistacia mutica, phenol 33 42 http://jhs.mazums.ac.ir/browse.php?a_code=A-10-593-9&slc_lang=fa&sid=1 Ramin Sarvani 10031947532846005015 10031947532846005015 Yes Cellular and Molecular Research Center and Department of Clinical Biochemistry, School of Medicine, Zahedan University of Medical Sciences, Zahedan, IR Iran Elhamh Damani 10031947532846005016 10031947532846005016 No chool of Public Health, Zahedan University of Medical Sciences, Zahedan, Iran Shahin Ahmadi sh.ahmadi398@gmail.com 10031947532846005017 10031947532846005017 No of Public Health, Zabol University of Medical Sciences, Zabol, Iran
