Summary: Different films containing pure chitosan and chitosan-coated zeolites were used for the sequestration of methyl orange dye. Results showed that CSZ3 had the highest adsorption capacity while CSZ4 had the lowest. Various analysis methods such as multilayer adsorption and pseudo-second order kinetics were used to explore the adsorption kinetics, equilibrium, and thermodynamics of the dye.

Summary: Chitosan/tannin/montmorillonite films are effective biosorbents for the removal of methyl orange from aqueous media. The films show high removal efficiency, large adsorption capacity, and follow pseudo second order kinetic and Langmuir isotherm models. Thermodynamic parameters suggest physical adsorption and exothermic behavior.

Summary: The study demonstrates that oxide modification greatly enhances the efficiency of aluminum powder for removing organic dyes, especially for methyl blue. LC/MS spectrum analysis reveals that dye molecules are broken down into small biodegradable organic molecules after reacting with OM-Al. Therefore, oxide modification activates aluminum powder for the removal of organic dyes.

Summary: Biochar prepared from sludge and liriodendron leaves modified by Fe3+ was used to remove methyl orange from aqueous solution. The modified biochar showed higher removal efficiency for MO than unmodified biochar. The adsorption kinetic model of pseudo-second-order and Freundlich isotherm models fitted well with the experimental data of MO in single and binary component systems.

Summary: Dye pollution is a significant problem in environmental protection. Bio-adsorbents, such as biobased sodium alginate-polyaniline nanotube (SA-PANINT) composite microbeads, have gained attention for their affordability, sustainability, and eco-friendly nature in wastewater treatment. Among the prepared microbeads, SA-PANINT-30 showed the best adsorption efficiency in experimental tests, indicating its potential as a highly efficient and low-cost adsorbent for the removal of synthetic anionic dyes from wastewater.

Summary: The interaction information between adsorbate-adsorbate and adsorbate-adsorbent is crucial for dye wastewater treatment. Different adsorbents exhibited varying adsorption efficiencies and capacities towards different dyes, with acidic conditions favoring MO adsorption by PsAX and alkaline conditions favoring IC and MB adsorption. Additionally, the competitive effect of MO towards IC adsorption was observed at low concentrations, but not at high concentrations due to intermolecular interactions.

Summary: Hectorite modified with CTAB is an efficient adsorbent for water treatment, with increased basal distances and mesopore area. The adsorption of methyl orange on CTAB-modified hectorite follows pseudo-second order kinetic and Sips models, and is a spontaneous exothermic process influenced by the entropy of adsorption.

Summary: This study investigated the elimination of methyl blue (MB) acidic dye from an aqueous solution using two types of modified montmorillonite. The adsorption efficiency of claytone and clay D2000 was 1.4 mg/g at pH 2 and 1.4 mg/g at pH 6, respectively. Pseudo-second-order was the best model to explain the adsorption process. The incorporation of MB/claytone and MB/clayD2000 into epoxy resin resulted in stylish colored epoxy nanocomposites with improved properties.

Summary: A nitrogen-rich activated carbon (PAnAC) was prepared from polyaniline (PAn) as a precursor, demonstrating a potential conversion of nitrogen-containing polymeric waste into a valuable adsorbent. PAnAC exhibited good adsorption performance, with multilayer coverage and a chemical sorption process. The adsorption capacity was optimal at higher MO concentration and lower adsorbent dosage, and the adsorption mechanism involved chemisorption and mass transfer and intraparticle diffusion processes.
