Removal of nonsteroidal anti-inflammatory drugs and analgesics from wastewater by adsorption on cross-linked β-cyclodextrin
Abstract
We present a method using the material in the form of cross-linked β-cyclodextrin (CD) showing high efficiency in the simultaneous removal of hazardous pollutants from sewage, such as diclofenac (DIC), ibuprofen (IBU), ketoprofen (KETO), naproxen (NAPR), salicylic acid (SALI) and tramadol (TRAM). The material is stable and particularly easy to regenerate. The sorbent probably remembers the shape of the contaminants, which increases its sorption capacity after the second use. The kinetics of the KETO adsorption process from one-, two- and three-component solutions are well described by the pseudo-second-order model. The maximum polymer capacity was 162.60 mg g−1. The interactions of KETO with CD were investigated, indicating that the main sorption mechanism is based on supramolecular interaction and uptake by a polymer network. The material is not sensitive to low pH and high salinity, so it can be used for the treatment of DIC, IBU, and KETO post-production wastewaters.
