Abstract

Rice husk is one of the abundant wastes, especially in agricultural countries. Rice husk waste has a
silica content of 95.80%, where the silica content can be utilized to make an adsorbent. One of the
adsorbents that can be made is Mobil Composition of Matter 41 (MCM-41), a material with a
hexagonal structure with a surface area to adsorb ibuprofen. Based on the results of the research that
has been done, MCM-41 synthesized with rice husk has the same characterization results as MCM-41
synthesized with commercial materials tetraethyl orthosilicate (TEOS). Fourier Transform Infrared
Spectroscopy (FTIR) characterization results show the absorption peak is at wave number 1068.58 cm1 which shows asymmetric Si-O-Si stretching vibrations and at 799.60 cm-1
region is symmetric Si-OSi stretching vibrations. X-ray diffraction (XRD) characterization results show an hexagonal crystal
form at 20 = 20o
-30o
. Scanning Electron Microscope (SEM) characterization results show particle of
2,664 um. Based on the results of the research that has been done MCM-41 synthesized from rice husk
can adsorb ibuprofen with Langmuir isotherm approach and Pseudo Second Order kinetics, and the
maximum adsorbing capacity is 34.48 mg/g
