This paper is devoted to specify properties of activated alumina, determine its adsorption characteristics, and calculate its adsorption rates as a significant parameter for designing adsorption process. In this regard, the most physical properties such as crush strength and particle size distribution of adsorbent were determined using modern and advanced devices. The Brunauer–Emmett–Teller (BET) test was carried out to determine the specific surface area, pore diameter and pore volume of the activated alumina which were 334.67 m2/g, 8.096 nm, and 0.0713 cm3/g, respectively. Additionally, chemical and morphological specifications such as pore size distribution of adsorbents assess textural properties of the activated alumina were characterized using X-ray fluorescence (XRF) and Barrett-Joyner-Halenda (BJH) analysis, respectively. Also, adsorption isotherm of the activated alumina were determined using Langmuir, Freundlich and BET models.
