Abstract This study focuses on the development of a novel self-cleaning nanofiltration membrane for efficient removal cationic dye methylene blue (MB) from industrial wastewater. The is composed vinyl resin (VR), cellulose nanofibrils (CNF), and titanium alpha aluminate (TAAL) nanoparticles. TAAL loading ranged 1 to 5 wt%, pH varied 10, initial MB concentration 10 50 ppm. Using dead-end filtration system, (VR/CNF@TAAL) with wt% at demonstrated excellent performances. It achieved remarkable 98.6% efficiency 30 ppm dye, maximum adsorption capacity 125.8 mg/g. kinetics analysis revealed that process followed pseudo-second-order model, indicating chemisorption mechanism. rate constant was determined be 1.2732 × –3 g mg −1 min . Freundlich isotherm model provided better fit (R 2 = 0.996) than Langmuir suggesting multilayer nanocomposite surface. In addition its high capabilities, exhibited cost-effectiveness environmental friendliness as an adsorbent membrane’s property further contributes sustainability by reducing need additional chemical treatments.

Nanomaterials for Environmental Applications

Опубликована: Янв. 1, 2023

The rapid growth in industrialization and population has resulted the generation permanence of a wide variety inorganic organic pollutants, posing potential risks to environment human health. degradation (either removal or reduction) sensing these pollutants from various environmental media (e.g., air, water, soil) are nowadays important problems worldwide. To address this issue, several nanotechnologies numerous nanostructured materials composites have been established for efficient remediation applications. This is ascribed their large surface area improved characteristics efficiency (like high reactive feature). current chapter reports such as filtration, photocatalysis, chemical reactions, absorption, adsorption, nanosensing, etc. It also offers an overview use environment. Novel materials, involving inorganic-based nanomaterials (NMs) zero-valent metal NMs, oxide-based silica-based NMs), carbon-based polymeric-based well nanocomposites were extensively reported discussed. These efficiently employed remediating halogenated herbicides, volatile compounds, chlorinated aromatic aliphatic hydrocarbons, pharmaceuticals, dyes, heavy metals, biological substances antibiotics, parasites, bacteria, viruses), gases (NOx, CO, SO2, etc.). Their efficiency, advantages, limitations compared Moreover, some directions future studies proposed.
