Phenol and its derivatives enter water sources through different natural and artificial routes. Phenol compounds are resistant to biologic degradation, soluble in water and are considered toxic to human and other species capable of causing unpleasant odor in water, mutations and birth defects. The objective of the present study was to investigate the potential of modified Saxaul ash to remove phenol from Aqueous Solutions in this experimental study, the effect of influential factors such as pH (2, 3, 5, 7, 8, 10, 12), contact time (5-120 min), adsorbent dose (0.1, 0.3, 0.5, 0.7, 0.9, 1.0 and 1.5 g L-1) and phenol initial concentration (10-200 mg L-1) was also determined. Adsorption isotherm was investigated using Freundlich, Langmuir and Temkin Isotherm Models. Results indicated that the maximum efficiency of modified Saxaul ash removing phenol was 91 that was achieved at pH of 3, 60 min contact time, 0.7 g L-1 adsorbent dose and phenol initial concentration of 100 mg L-1. In addition, adsorption isotherm study showed the most fitness of data into Langmuir Adsorption Model (R2 = 0.996). © Medwell Journals, 2016.
