“…Several column adsorption studies were already performed using fibrous adsorbent, synthesized using radiation-induced graft polymerization showing extremely high performance in the adsorption of Hg, Cs and As [6,34,35]. Based on the data presented above, the synthesized amino and iminodiacetic-type adsorbent shows good adsorption capacity and proved to have a potential in the removal of chromium and cadmium in wastewater treatment.…”

Metal ion adsorbents bearing amino and iminodiacetic groups were synthesized via radiation-induced graft polymerization of emulsified glycidyl methacrylate monomer from polypropylene non-woven fabric followed by subsequent reaction of the epoxide functional groups with ethylenediamine or iminodiacetic acid. The resulting amino-and iminodiacetic-type adsorbents exhibited excellent Cr(VI) and Cd(II) adsorption performance, respectively, based on the results of batch and column adsorption experiments. The Cr(VI) ions bound on the amino-type adsorbent were desorbed with 2M NaOH solution, while the bound Cd(II) ions were effectively stripped off from the iminodiacetic-type adsorbent by using organic acids, such as citric, acetic and oxalic acid. Both adsorbents showed more than 94% adsorption efficiency after five consecutive adsorption-desorption cycles. The adsorption dynamics of the metal ions to the synthesized grafted adsorbents obeys pseudo-second order kinetics. The radiation-grafted adsorbents exhibited comparable, if not better performance than commercially available ion-exchange resins. Continuous fixed bed column adsorption was performed, and the breakthrough curves were plotted at varying feed solution flow rate. The column-packed amino-type adsorbent can treat more than 4000 BV (> 1500 mL) of 3 ppm Cr(VI) solution at 155 BV hr −1 flow rate before the breakthrough. Lastly, the amino-type adsorbent was successfully applied in the treatment of actual tannery wastewater, with the resulting effluents meeting the national standards.

“…Especially, the disaster areas caused by an accident at the Fukushima Daiichi Nuclear Power Station widely distributed radioactive materials. Therefore, we have developed a high-performance adsorbent for cesium (Cs) removal [1]. During usage of our Cs removal system, the proliferation bacteria were observed in discharged water effluent.…”

To obtain the safety of drinking water, an antibacterial material was prepared by loading silver (Ag) onto fibrous iminodiacetate (IDA) adsorbent, which was synthesized by radiation-induced graft polymerization of glycidyl methacrylate and subsequent chemical modification of the produced epoxy group to an IDA group (IDA-Ag). A total amount of loaded Ag on the IDA-Ag fabric was 0.4 mmol-Ag/g-fabric. From an observation of the IDA-Ag fabric cross section by a scanning electron microscope energy dispersive X-ray spectrometer, Ag was distributed to IDA layer uniformly. As a result of evaluating antibacterial effects by the column mode water flow test with stream water, the effective Ag concentration was monitored 0.05 ppm at irrespective flow rate which was functioned to the antibacterial performance. The antibacterial effects for general bacteria were indicated until BV (BV: steam water volume/IDA-Ag fabric volume) 6000, and for colitis germ legions were completely disinfected until BV 6000.
