Fabrication of Manganese Oxide-silica Based Functional Polymer Composite Membranes and Their Environmental Application

In-Depth Photocatalytic Degradation Mechanism of the Extensively Used Dyes Malachite Green, Methylene Blue, Congo Red, and Rhodamine B via Covalent Organic Framework-Based Photocatalysts

“…Furthermore, only 47% of all dyes are biodegradable in nature, and as a consequence, diverse physical and biological method regarding approaches for remediation were reported during the last two decades [28]. The developed approaches for dye and other organic-pollutant processing are physical methods (adsorption, ion-exchange, chemical precipitation, chemical degradation, flocculation, coagulation, and ultra-filtration), chemical methods [29][30][31][32] (electro-catalytic degradation, the photochemical process, the Fenton process, oxidation, irradiation, ozonation and photocatalytic degradation) [33], and biological methods (enzymatic activity, microbial activity and phytoremediation) [18,20,[34][35][36][37][38][39][40][41][42]. Coagulation and sedimentation approaches are frequently implemented; however, these methods lead to the accumulation of pollutants, which are challenging to manage.…”

Interfacial Polymerization on Polyethersulfone Ultrafiltration Membrane to Prepare Nanofiltration Layers for Dye Separation

“…Each method has its own advantages and limitations in terms of cost, efficiency, feasibility, and environmental impact. Compared with traditional dye separation technology, membrane separation technology has the advantages of high energy efficiency, simple operating conditions, low cost, and environmental friendliness and is increasingly being used in water treatment [14,15]. Polyethersulfone (PES) membrane is an excellent membrane separation material for water purification and recovery due to its good mechanical properties and chemical stability [16,17], and it is widely used in dye separation.…”
