Effects of acidity on the mesoporous carbon CMK-3 structure during Ibuprofen molecule adsorption

Abstract

A novel molecular sieve based mesoporous Carbon CMK-3 as adsorbent were prepared by hard templating method using sucrose and mesoporous silica SBA-15 as source of carbon and nanocast, respectively. The impregnation sequence of sucrose onto SBA-15 catalysed by sulphuric acid and followed by pyrolysis process at 900°C for 6 h. The mesoporous Carbon CMK-3 adsorbent were characterized by (Fourier transform infrared spectrometer) FTIR, scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy dispersive spectroscopy (EDS) techniques. The effects of acidity on ibuprofen adsorption performance were investigated using UV-Vis. The result shows that there was a strong effect between acidity condition and adsorption performance. The high acidity condition did not change the big part of mesoporous Carbon CMK-3 microstructure. The shrinkage of mesoporous carbon CMK-3 structure showed a better yield of total ibuprofen adsorbed which reached loading degree up to 65 (%wt).
