Rice Husk–Sugarcane Bagasse-Derived Silica for Methylene Blue Removal in a Fixed-Bed Column: Synthesis and Characterization
Methylene blue is a persistent dye that can impair light penetration and aquatic photosynthesis, while its chemical stability complicates conventional wastewater treatment. This study developed silica from a 3:1 mixture of rice husk and sugarcane bagasse, enabling the simultaneous valorization of two abundant agricultu...
