Textile dye removal using diatomite nanocomposites: a metagenomic study in photosynthetic microalgae-assisted microbial fuel cells.

ABSTRACT: In this study, Coomassie brilliant blue (CBB), brilliant green (BG), and rhodamine (Rh) dyes were used to simulate dye-rich wastewater. Adsorption and degradation of these dyes (2 μM, 10 μM, and 30 μM) on diatomite (DE) were evaluated under light (L) and dark (D) conditions. The adsorption of dye-DE composites followed pseudo-second-order kinetics at all concentrations and conditions had R ² > 0.99, thus showing a good fit. The calculated equilibrium adsorption amount q _e,(cal) was coherent with the value of experimental q _e,(exp). The poorest adsorption and photocatalysis occurred at 30 μM, prompting the functionalization of dyes with TiO₂ and Fe₃O₄ nanoparticles (NP(s)). The highest dye degradation eff
