Abstract

This study focuses on the synthesis and characterization of mesoporous MCM-41, a highly effective material for removing Methylene Blue dye from water. The mesoporous material was synthesized using an eco-friendly rice bran oil template by sol-gel approach from tetraethyl orthosilicate. The synthesized material was characterized using various spectroscopic techniques, such as DRS-UV, FTIR, PXRD, BET, SEM, EDX, HR-TEM, and TG-DTA analysis. The analyses are revealing a mesoporous structure with impressive properties of high absorbance, hexagonal structure, surface area of 385.28 m²/g, pore volume of 0.5875 cm³/g, pore diameter of 6.1 nm and good thermal stability. Adsorption studies evaluated the effects of dye concentration, adsorbent dosage, and adsorption kinetics, demonstrating that MCM-41 follows a monolayer adsorption mechanism with pseudo-second-order kinetics. The maximum removal efficiencies of the Methylene Blue dye were found to 88% with 0.05 g of the MCM-41.
