Ibuprofen (IBU) is a non-steroidal anti-inflammatory drug that is used for medical treatment in human and animals. Since IBU is not entirely absorbed in the body, a portion of it is obviously defecated and entered into the aqueous environment. Besides, IBU can be fed to the natural environment through pharmaceutical industry wastes. The existence of IBU in the nature can have traumatic effects on living organisms. In fact, it can widely endanger human life and the health of the natural habitat. Therefore, researchers have intended to discover methods to remove IBU from the environment or reduce its existence down to minimum. Finally they applied several different methods for doing. So, in this paper, we examine quite a few procedures to discover the advantages and disadvantages of each.
