TL;DR: A weak-base anion exchange fiber named FVA with primary amino groups for selective and rapid removal of arsenate species was prepared by means of electron irradiation induced liquid phase graft polymerization of N-vinylformamide onto polyethylene coated polypropylene fibers and by the subsequent alkaline hydrolysis of amide group on the grafted polymer chains.

TL;DR: In this paper, a uranium-specific nonwoven fabric was used as the adsorbent packed in an adsorption cage 16 m{sup 2} in cross-sectional area and 16 cm in height.

TL;DR: The characterization of the surfaces containing amino groups revealed that the membrane potentials are proportional to amino-group densities and contact angle hysteresis, which indicates that membrane potential could be used as an indicator for estimating bacterial adhesion to the EA and DEA sheets.

TL;DR: In this paper, a cografting of methacrylic acid (MAA) with acrylonitrile (AN) onto polypropylene fibers and subsequent conversion of the produced cyano group to an amidoxime group by reaction with hydroxylamine was performed.

TL;DR: The optimum value of the weight ratio of AN/MAA = 60/40 in the monomer mixture was observed both in a submerged mode at an ocean site and in a flow-through mode in the laboratory to enhance the uranium adsorption from seawater.
