Removal of amoxicillin and ampicillin using manganese dioxide/montmorillonite composite

Original language description

BACKGROUND: Clay-based materials represent great potential for the development of efficient and environmentally friendlysorbents. The study focuses on a laboratory-obtained manganese dioxide/montmorillonite (MnO2/MMT) composite for removalof two types of antibiotics–amoxicillin (AMX) and ampicillin (AMP)–from aqueous solution.nRESULTS: The composite was successfully prepared using a reduction procedure involving the reaction between potassium per-manganate (KMnO4) and hydrochloric acid (HCl) to form MnO2followed by the addition of MMT. X-ray analysis, scanning elec-tron microscopy, X-rayfluorescence and Fourier transform infrared spectroscopy were performed for characterization ofphysicochemical and structural properties, simultaneous thermogravimetry and differential scanning calorimetry for estima-tion of thermal stability and high-performance liquid chromatography for determination of antibiotic equilibrium concentra-tions in aqueous solution. The precipitated MnO2component, manifested by longfibers, corresponded to the tunnelstructure of cryptomelane. In the case of MnO2/MMT it is evident that MnO2developed shortfibers with the participation ofthe MMT matrix. The thermal data suggested that the MnO2phase upon contact with the clay support showed better thermalstability. Thefinal decomposition of Mn2O3was shifted to higher temperature of 985°C. Adsorption procedure in a batch reg-imen showed sufficient sorption ability for both antibiotics with over 90% efficiency. For AMP the value ofqmaxwas about45 mg g−1and for AMX it was only 21 mg g−1.nCONCLUSIONS: The results provided valuable information for the design of a potentially inexpensive clay-based adsorbent anddemonstrated the removal of two types of broad-spectrum⊎-lactam antibiotics from aqueous solution to a sufficient degree.
