Abstract

With the increase in population, emerging chemical pollutants such as pharmaceutical compounds have entered water sources that conventional water purification methods cannot completely remove. Therefore, it is necessary to remove them considering the dangers of these pollutants and their toxicity to the environment and human society. In this research, iron oxide-magnetized bentonite nanocomposite was synthesized in situ using the co-precipitation method to remove acetaminophen from water sources. The structure of the synthesized nanocomposite was investigated using FTIR, BET, XRD, EDX and FSEM analyses and its performance in acetaminophen removal was studied. The results showed that the synthesized iron oxide-magnetized bentonite nanocomposite has an appropriate performance (100% in 30 min) in the process of acetaminophen removal. The test conditions (nanocomposite amount, time, pH and acetaminophen concentration) were optimized. The highest amount of acetaminophen removal was obtained by using iron oxide-magnetized bentonite nanocomposite with a reaction time of less than 30 min, pH= 4, initial acetaminophen concentration of 25 mg/L and adsorbent concentration of 1 g/dL.
