Removal of metal cations from wastewater using recycled wool-based non-woven material

Abstract

In this study, the effect of low-temperature air plasma, biopolymer chitosan and hydrogen peroxide treatment of recycled wool-based non-woven material on metal cation uptake was investigated. Recycled wool-based material either as an untreated or modified material showed ability to bind all investigated metal cations in the following order: Pb2+ gt Cu2+ gt Zn2+ gt Co2+. Material performed good selectivity due to distinct sorption rates of studied metal cations. .

U ovom radu je ispitan uticaj obrade netkanog materijala na bazi vune kao sekundarne sirovine niskotemperaturnom plazmom, biopolimerom hitozanom i vodonik-peroksidom na sorpciju katjona metala. Materijal na bazi vune kao sekundarne sirovine bilo kao neobrađen ili modifikovan, poseduje sposobnost vezivanja katjona metala prema sledećem redosledu: Pb2+ gt Cu2+ gt Zn2+ gt Co2+. Materijal pokazuje dobru selektivnost usled različite brzine sorpcije ispitivanih katjona metala. .
