The development of adsorbents capable adsorbing both anionic and cationic dyes in wastewater treatment remains a challenge. This study presents the successful fabrication Nb2O5-MgAl layered double hydroxide (LDH) nanocomposites for effective removal methylene blue (MB) Congo red (CR) via one-step hydrothermal method. Incorporating small amount Nb into MgAl-LDH proved to be an strategy creating nanocomposite materials with dual characteristics. material's morphological crystalline structures were confirmed using FESEM-EDS XRD. during material preparation led remarkable enhancement adsorption capacity - up 3.4-fold 9-fold increases CR MB, respectively. kinetic point zero charge analysis that onto adsorbent surfaces occurred ionic interaction mechanism. These findings offer promising alternative fabricating dual-functional adsorbents, enhancing effectiveness dye technologies.

The discharge of synthetic dyes into water bodies poses severe environmental risks due to their toxic and recalcitrant nature. This study explores the enhancement photocatalytic properties cerium dioxide (CeO2) nanorods by doping with lanthanum (La) improve efficacy in degrading aqueous solutions Congo red dye. CeO2 were synthesized via a hydrothermal method subsequently doped varying concentrations La. scanning electron microscopy (SEM) images confirmed rod-like structures (nanorods) observed for all samples, while energy-dispersive X-ray spectroscopy (EDX) homogeneous incorporation La matrix. diffraction (XRD) spectra demonstrate lattice distortion substitutional defect. Photocatalytic experiments revealed that La-doped exhibited significantly enhanced degradation capabilities compared undoped counterparts, achieving up 3-fold kinetics ((30 ± 2) × 10−3 min−1) counterparts ((11.5 0.4) min−1). Influence various parameters affect photocatalysis performance (i.e., contact time, initial dye concentration, catalyst dosage, solution pH value) also investigated. Radical scavenger reveal superoxide radicals play dominant role process. Collectively, these findings confirm strategic not only enhances overall efficiency but tailors activity towards specific pollutants through radical-mediated pathways.

This study presents a novel composite nanofiber membrane combining polyacrylonitrile/polyvinylidene fluoride (PAN/PVDF) electrospun nanofibers with locally sourced zeolite from Sumatera, Indonesia, for pollutant dye filtration. The Ze-PAN/PVDF has 100% methylene blue rejection even after five filtration cycles permeation flux of 185 L m−2 h−1 bar−1. is highly selective, efficiency cationic dyes (i.e., and crystal violet) vs. 78% 1% anionic Congo red methyl orange, respectively). For the dyes, mechanism mainly governed by electrostatic attraction, while size exclusion becomes more dominant dyes. Overall, these results demonstrate potential use in wastewater treatment applications.
