Biodegradable hollow zein nanoparticles for removal of reactive dyes from wastewater

Removal of hydrolyzed Reactive Black 5 from aqueous solution using a polyethylenimine–polyvinyl chloride composite fiber

“…In particular, reactive dyes are broadly used to color cellulose and rayon textiles due to their favorable characteristics such as bright color, water-fastness and easy dyeing operations [1,2]. The amount of reactive dyes stands about 45% as regards the annual production (700,000 tons) of commercially available dyestuffs [3].…”

Kinetics and optimization on discoloration of dyeing wastewater by schorl-catalyzed fenton-like reaction

“…1 Effluent containing reactive dyes from textile dyeing and finishing industries is a significant source of environmental pollution. 2 With the increasing concern about environment protection, removal of dyes from wastewater has become a significant issue. About 45 % of the annual production (700,000 tons) of commercially available dyestuffs belongs to the reactive dye class.…”

Nanoparticles Derived from Plant Proteins for cOntrolled Release and Targeted Delivery of Therapeutics

“…Combining with water soluble sacrificial templates, hollow nanostructures could be obtained from zein. The hollow nanoparticles had considerably highloading capacities, up to 369 mg/g for positively charged metformin at equilibrium concentration of 3 g/l [4], and 1016 mg/l for negatively charged dye at pH 10 with high salt concentration [5]. In vivo studies indicated that zein nanoparticles loaded with 5fluo rouracil mainly accumulated in liver and remained in blood for longer than 24 h, proving its potential of avoiding opsonization [6].…”
