Adsorption efficiency of a new adsorbent towards uranium and vanadium ions at low concentrations

Kavakli, P. A.*; Seko, Noriaki; Tamada, Masao; G$"u$ven, O.*

A new type of fibrous adsorbent with excess amidoxime groups was synthesized by radiation-induced graft polymerization. Glycidyl methacrylate (GMA) was first radiation-grafted on polyethylene-coated polypropylene nonwoven fabrics and chemically modified with 3,30-iminodipropionitrile [NH (-CH$$_{2}$$-CH$$_{2}$$-CN)$$_{2}$$] (IDPN), which was further reacted with hydroxylamine to obtain graft chains containing two amidoxime groups per graft repeating units. The adsorption properties of this new adsorbent for uranium (U), vanadium (V), lead (Pb), copper (Cu), and cobalt (Co) ions at low concentrations (3.3-1000 ppb).
