Abstract
An adsorbent containing glycidolized poly(vinylamine) ligand with a remarkably high boron selectivity was prepared by modification of fibrous polyethylene/polypropylene (PE/PP) nonwoven sheet by radiation induced grafting (RIG) of N-vinylformamide (NVF) followed by hydrolysis and subsequent functionalization with glycidol. The variation of the absorbed dose and monomer concentration was used to control the content of the grafted P(NVF). Fourier transform infrared (FTIR), X-ray photoelectron spectroscopy (XPS) and scanning electron microscope (SEM) were used to verify the chemical and morphological changes accompanied the applied procedure and boron loading. The fibrous adsorbent with fully hydrolyzed P(NVF) grafts of 120% exhibited a superior boron adsorption capacity of 21.4 mg/g compared to commercial and researched counterparts at pH 7.
