Abstract

Al-MCM 41 is an important material for reducing methylene blue waste through adsorption
technique. The MCM 41 adsorption was mostly influenced on the MCM 41 framework that was
built. Hence, the alumina incorporated on the MCM 41 will change the MCM 41 frameworks to
become negative charge so that it influences the adsorption process of methylene blue. In this
study evaluated the effect of alumina on MCM 41 frameworks in the adsorption process of the
methylene blue. The research resulted that Al-MCM 41 has been synthesized directly, it showed
any different on MCM framework because alumina caused the isomorphic substitution with Si
atom. This indication can be identified from the shift of FTIR wavenumbers at 795 cm-1 that
showed any different vibration of Si-O-Si and Si-O-Al, while the decreasing intensity of XRD
indicated any different crystalinity formed. Al-MCM 41 has a good ability as an adsorbent for
removing methylene and it is more effective than Si-MCM 41. Al-MCM 41 follows the adsorption
model appropriate the Langmuir isotherm equation.
