The rapid growth of industrialization has resulted in the release large quantities pollutants into environment, especially dyes and heavy metals, which are environmentally hazardous for humans animals. It is considered as most promising friendly route to develop green materials by using modification method, no negative impact on environment. In this work, material polylactic acid (PLA) was used substrate material, a novel method polydopamine (PDA)-assisted polyethyleneimine (PEI) grafting developed. electrospun PLA fibers mainly composed stereocomplex crystallites, were achieved via electrospinning poly(l-lactic acid) poly(d-lactic acid). water-soluble PEI grafted onto PDA-modified through glutaraldehyde-assisted cross-linking reaction. prepared composite can be degraded, meets requirements sustainable development. potential application such wastewater treatment intensively evaluated. results show that at appropriate fabrication conditions (PDA concentration 3 g·L–1 molecular weight 70,000 g·mol–1), exhibit maximum adsorption capacities 612 398.41 mg·g–1 methyl orange (MO) hexavalent chromium [Cr(VI)], respectively. Simultaneously, about 64.79% Cr(VI) adsorbed reduced Cr(III). above have good development prospect field treatment.

Emerging chromium (Cr) species have attracted increasing concern. A majority of Cr species, especially hexavalent (Cr(VI)), could lead to lethal effects on human beings, animals, and aquatic lives even at low concentrations. One the conventional water-treatment methodologies, adsorption, remove these toxic efficiently. Additionally, adsorption possesses many advantages, such as being cost-saving, easy implement, highly efficient facile design. Previous research has shown that application different adsorbents, carbon nanotubes (carbon (CNTs) graphene oxide (GO) its derivatives), activated carbons (ACs), biochars (BCs), metal-based composites, polymers others, is used for removal from contaminated water wastewater. The progress in recent years are reviewed, mechanisms also discussed development trend treatment by proposed.

Abstract Due to their unique properties such as outstanding specific surface areas, aerogels can potentially offer a cost-effective and efficient water wastewater treatment solution thereby solving the worldwide ever-growing pollution conundrum. This review explores developments progress in application of cellulose, graphene, cellulose-graphene composite addressing challenges. The objective this study was critically state-of-the-art with respect synthesis methods application, effectiveness performance treatment. It is evident from that aerogel production be scaled up easily still need developed enable commercial viability Furthermore, mechanical aerogels, particularly stiffness strength, are hinderance expanding utility. potential for functionalization through fabrication nanocomposites or incorporation functional groups recognized viable method enhance other advanced industrial-scale applications. Graphene-cellulose have enhanced properties, removal capacities efficiencies pollutants compared prepared individual materials. regeneration ability reusability make them an attractive option practical Although applications apparent, impact production, utilization subsequent disposal on sustainability environmental yet fully studied.
