Abstract Dye wastewater is becoming one of the most significant sources water pollution, and its impact on human survival immeasurable. In this study, we successfully synthesized a nanofiber membrane with environmentally friendly efficient properties using electrospinning mixture sodium alginate (SA) copper oxide (CuO) nanoparticles, aimed at effective dye removal. The adsorption performance SA/CuO was evaluated cationic methylene blue (MB). maximum capacity increased significantly addition CuO reaching value 1633.4 mg g −1 , almost twice as much that pure SA membrane. kinetics follows pseudo‐second‐order model, where chemisorption acts rate‐limiting step. isotherm data indicate monolayer. nanofibrous membranes showed better removal under an alkaline environment. After four cycles adsorption/desorption, MB efficiency remained 70.1% original capacity. nanoparticles facilitated dyes, while form easily recoverable reusable. Therefore, as‐prepared composite potentially favorable adsorbent material for treatment applications.

Properties of cationized alginate fibers dyed with direct dyes

Journal of the Textile Institute, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 9

Published: Nov. 4, 2024

In this study, we used 3-chloro-2-hydroxypropyltrimethylammonium (CHPTAC) chloride to cationize alginate fibers obtain dyeable modified fibers. After modification, the surface of was positively charged. Direct dyes can be dye without adding salt. The results FTIR and XRD tests showed that there no significant change in structure after modification process. XPS CHPTAC successfully combined with SEM, single-fiber strength, thermal stability analysis indicated both dyeing processes did not affect strength flame-retardant properties addition, have good dyeability color fastness. This process presents a novel method for using salt, it involves low cost simple steps.

Bu çalışma anyonik (reaktif turuncu 16 (RO16), direkt sarı 50 (DY50), asit mavisi 25 (AB25) ve katyonik (malakit yeşili (MG), metilen (MB)) gibi çeşitli boyaların kitosan, lesitin mantar özütü ile hazırlanan nanopartiküllü biyonanosorbent (KLcPEE)’in adsorpsiyon kapasitesini analiz etmektedir. Biyosorbentin yüzeyini karakterize etmek için FE-SEM FTIR teknikleri kullanılmıştır. KLcPEE biyonanosorbent, MG, MB, RO16, DY50 AB25'in 100 mg/L sulu ortamı sırasıyla 56,77, 59,76, 74,33, 83,45 147,30'luk maksimum boya giderme kapasitesi sergilemiştir. biyonanosorbentteki tüm süreci, psödo 1.ci dereceden kinetik modeliyle uyumlu olduğu gözlemlenmiştir. Genel olarak, bu çevre dostu, sürdürülebilir, biy-olojik bir sunumakta KLcPEE, atık suda hızlı etkili organik adsorpsiyonu önemli potansiyel sergilemektedir.
