Application of nano-TiO ₂ @adsorbent composites in the treatment of dye wastewater: A review

Journal of Engineered Fibers and Fabrics, Год журнала: 2025, Номер 20

Опубликована: Янв. 1, 2025

A large amount of wastewater with a high dye content is discharged from the textile printing and dyeing industry. Synthetic dyes, which are essentially exogenous chemicals, predominantly exhibit property poor biodegradability. Consequently, they capable persisting stably within environment over protracted time spans. The high-chroma not only results in severe water pollution but also breaks ecological balance, thereby rendering it pivotal formidable facet realm industrial treatment. treatment prior to its discharge utmost necessity. This article offers relatively comprehensive exposition methods for wastewater, specific focus on adsorption method, photocatalysis their respective characteristics. Nano-TiO 2 @adsorbent composites, integrate advantages photocatalysis, have been widely studied wastewater. paper provides broad overview classifications, adsorption-photocatalytic mechanism, influencing factors nano-TiO composites. composites processes adsorption, catalysis, degradation, significantly improving efficiency photocatalytic degradation organic pollutants by titanium dioxide catalysts. Furthermore, suggestion research development photocatalyst @textile composite materials put forward this article.

Synthesis of a new catalyst (Cu-MOF235) and its optimization for dye removal by wet-oxidation

Research Square (Research Square), Год журнала: 2024, Номер unknown

Опубликована: Фев. 9, 2024

Abstract This study focuses on enhancing the catalytic properties of copper-modified MOF235 (Cu-MOF235) in wet-oxidation for methylene blue (MB) removal from aqueous solutions, while also optimizing process conditions. The impact variables such as catalyst dosage (0.005–0.02 g), pH (4–10), temperature (20–40°C), reaction time (5–60 min), and type dye is investigated. SEM, EDX, FTIR, XRD techniques were used to investigate structural physical characteristics synthesized catalyst. statistical approach Design Experiments (DOE) systematically establishes relationship between factors output. Increasing boosts active sites faster degradation or transformation compounds, although diminishing returns may arise. Elevated temperatures reduce activation energy, increasing MB rate. Cu-MOF235 surpasses due enhanced sites, robust chemical interactions, surface modifications, potential synergies, degradation, altered solution chemistry. presence aeration can proceed through a series steps by adsorption, oxygen, formation intermediate products, complete desorption. research underscores significant modification offers insights into processes.
