Abstract
Natural micromaterials including micro and mesoporous minerals are essential components of sophisticated material cycles and are well known for the biocompatibility and renewability. Meanwhile, feldspar is a rock-forming aluminosilicate mineral that contains alkali metals and is very abundant in nature. The MCM-48 mesoporous material with its 3D pore structure has been widely used in various applications, especially as adsorbents. However, its less hydrothermal nature limits optimal use, consequently, a method such as the combination with micropore feldspar into the mesopore framework is needed to overcome this limitation. Therefore, this study aims to synthesize feldspar mineral composites with MCM-48 by growing the layer on a crystal core using the hydrothermal method for 24 hours at 110C and calcination for 5 hours at 550C. The feldspar minerals and aluminosilicate composites formed were characterized by XRD, FTIR, SEM, and BET. The pore size distribution using DFT method shows a wide mesoporous distribution centered on 23-27Å (from MCM-48) and the presence of low peaks between 6-9Å, thereby indicating a pore distribution identical to the microporous pores of feldspar. The results showed that the MCM-48 modified feldspar composite has been integrated into a single functional unit with new improved physical and chemical properties. Therefore, this composite has the potential to be developed into new materials for multilevel adsorption systems to increase the effectiveness of adsorbents in wastewater containing multi-metals.
