Preparation of mesostructure amorphous aluminum-methionine and its potency as adsorbent

Abstract

An amorphous metal-amino acid contains metal based on Aluminium and Methionine as a ligand, was synthesized. The fabricated amorphous Al-Methionine (a-AM) is done in water solvent under moderate thermal conditions. The advantages of using bio ligands, one of which is amino acid, can be used to biologically compatible material. The synthesis was optimized changing chemical (metal and ligand molar ratio) and process (temperature, time) parameters. The a-AM characterization was carried out by XRD, FTIR spectroscopy, FESEM, also gas sorption measurement (BET). From the N2 adsorption/desorption isotherm, the a-AM is classified as a type IV and has a mesoporous structure. The produced a-AM has a SBET area 287 m2 g−1, pore size 0.996 cm-3 g−1 and mean pore diameter 13.85 nm. After demonstrated in the dye adsorption, this material has potency as an adsorbent.
