A promising way to prepare anion-exchange materials is to introduce positively charged amine groups on polymers. In this study, polyacrylonitrile (PAN) ultrafiltration membranes were modified with amine functionalities on the mem-branes. The success of the modifications was demonstrated using infrared spectroscopy and zeta potential measurements. Additionally, the arsenate adsorption was analyzed. The modified membrane showed arsenate adsorption 5 times higher than the pristine PAN membrane.en1522-26402021913961400John Wiley & Sonshttps://creativecommons.org/licenses/by-nc-nd/4.0/Amine modificationAnion adsorbing materialsChromate/arsenatePAN membranesWater purificationChemieTechnikIngenieurwissenschaftenJournal Article10.15480/882.360910.1002/cite.20210003710.15480/882.3609Other
