Silk fibroin and silk fibroin-gold nanoparticles nanocomposite films: sustainable adsorbents for methylene blue dye

Preparation, characterization, and methylene blue dye adsorption study of silk fibroin–graphene oxide nanocomposites

“…15 Treating effluents containing these dyes is challenging. Additionally, most conventional water-treatment techniques [16][17][18][19][20] have serious restrictions, including high expenses, rigorous conditions and the formation of by-products. 21,22 Therefore, it is necessary to develop a technology that is efficient, cost-effective, and nature friendly for removing dye constituents from wastewater.…”

“…37,38 However, various polymorphs of broin with a variety of dopants have exhibited tremendous adsorption capacities over native SF. 18,39 Recently, GO, a carbon-based nanomaterial, has been mostly used in wastewater treatment as its adsorption ability towards MB is excellent. 40 The numerous oxygen-containing groups on the surface and large surface-areato-volume ratio of GO aid in its effective interaction with dye molecules.…”
