A comprehensive review on adsorptive removal of azo dyes using functional materials

AQUA - Water Infrastructure Ecosystems and Society, Journal Year: 2024, Volume and Issue: 73(2), P. 266 - 285

Published: Feb. 1, 2024

Abstract The shortage of freshwater resources caused by azo dye pollution is an acute global issue, which has a great impact on environmental protection and human health. Therefore, the use new strategies for designing synthesizing green, efficient, economical materials removal dyes required. Among various methods dyes, adsorption using advanced functional materials, including nanomaterials, metal oxides, oxides–polymer composite, biomaterials, porous have attracted significant attention over past few years because their capabilities brilliant efficiency, high selectivity, quick response, reversibility, flexibility in operation, less harmful by-products. In this review, we report general design principles underlying above-mentioned and, particular, highlight fundamental mechanisms effect conditions; also, current challenges opportunities exciting field been emphasized, fabrication, subsequent treatment, potential future applications such materials.

Efficient extraction of textile dyes using reusable acrylic-based smart polymers

Journal of Hazardous Materials, Journal Year: 2024, Volume and Issue: 476, P. 135006 - 135006

Published: June 24, 2024

Water pollution from industrial or household waste, containing dyes the textile industry, poses a significant environmental challenge requiring immediate attention. In this study, we have developed crosslinked-smart-polymer film based on 2-(dimethylamino)ethyl methacrylate copolymerized with other hydrophilic and hydrophobic commercial monomers, its efficacy in removing 21 different was assessed. The smart polymer effectively interacts adsorbs dyes, inducing noticeable colour change. UV-Vis spectroscopy analysis confirmed removal efficiency exceeding 90% for anionic external diffusion identified as primary influencing factor process kinetics, consistent both pseudo-first-order kinetics Crank-Dual model. Isothermal studies revealed distinct adsorption behaviors, indigo carmine adhering to Freundlich isotherm while others conformed Langmuir Permeation fluorescence analyses corroborated observations, verifying surface adsorption. Significantly, our proof-of-concept demonstrated resilience of smart-film common fabric softeners detergents without compromising capacity. Additionally, material exhibited reusability (for at least 5 cycles), durability, good thermal mechanical properties, T5 T10 values 265°C 342°C, respectively, Tg 168°C, water swelling percentage 54.3%, thus confirming stability suitability application. Dyes released during laundry processes should be classified "hazardous materials" owing their toxicity towards aquatic organisms, potential disrupt ecosystems harm biodiversity. This paper discusses development novel acrylic form, engineered extract toxic dyes. study directly contributes mitigating impact associated fashion industry domestic use textiles. It can implemented an personal scale, thereby encouraging more sustainable practices promoting collaborative citizen science efforts
