    Antibacterial activated carbon fibre derived from phenolic resin fibre by use of co-graftpolymerization (1993)

    Notes: Abstract Phenolic-resin fibre was co-graftpolymerized with methyl methacrylate and methacrylic acid. The weight of the fibre increased by 26% after grafting. The grafted fibre was soaked in silvernitrate solution to introduce silver ion on methacrylic acid in the graft by an ion-exchange reaction, followed by carbonization at 900 °C for 30 min under a nitrogen stream and activation at 900 °C under a steam stream. After activation for 40 min, the resulting fibre showed a silver content of 8.3 wt% a specific surface area of 1300 m2g−1 and antimicrobial activity against Staphylococcus aureus and Escherichia coli. The average crystallite size of the silver in this fibre was 30 nm, which suggests co-graftpolymerization is a useful technique to disperse fine silver particles in the activated carbon fibre. After soaking in flowing tap water for 10 and 20 days, this activated carbon fibre lost about 50 wt% of silver but kept its antibacterial activity.

    Preparation of fibrous adsorbents containing amidoxime groups by radiation-induced grafting and application to uranium recovery from sea water (1993)

    Notes: Polypropylene fibers and polyethylene hollow fibers were used as trunk polymers and were irradiated by electron beams with a dose of 200 kGy under N2 atmosphere. Grafting of acrylonitrile to those irradiated fibers was carried out at 40°C for different periods of time. The degree of grafting was determined as a function of time. The fibrous adsorbents containing amidoxime groups were prepared by the reaction of acrylonitrile-grafted polymers with 3% hydroxylamine in a methanol-water mixture (1 : 1). Distribution of copper ions complexed with amidoxime groups at various adsorption times was obtained by electron-probe X-ray microanalysis. The amidoxime groups are homogeneously distributed in the cross section of fibrous adsorbents. The fibrous adsorbents based upon polypropylene fiber of 40 μm showed a remarkable kinetic behavior for Cu2+. Even after 15 min, the adsorption capacity was 2.32 mmol Cu2+ per gram of fiber. Also, the functionalization with hydroxylamine was carried out at different conditions to compare the adsorption characteristics of the resultant adsorbents. Despite having superficially different properties (elemental microanalysis, ion-exchange capacities, adsorption capacity for UO2+2), the polypropylene-based fibrous adsorbents showed similar adsorption properties for uranium from sea water. The adsorption tests proved the performance of the polypropylene-based fibrous adsorbents as a promising material for uranium recovery from sea water. In addition, uranium uptake of fibrous adsorbents increased in proportion to the volume of sea water. © 1993 John Wiley & Sons, Inc.

    Synthesis of functional polymers by radiation-induced grafting of acrolein onto polyethylene film (1989)

    Notes: Acrolein was grafted onto polyethylene film with radiation energy in order to make functional polymers containing hydrazone, oxime, and oxyacid. The kinetic analysis of the grafting reaction revealed that the irradiation dose affected not only the initiation but also the propagation and termination steps. The activation energies were 12.5 kcal/mol for propagation and 23.3 kcal/mol for termination, respectively. All the introduced aldehyde groups, free, hydrolyzed, and used for ring formation, participated in the reaction with phenylhydrazine. The conversions of aldehyde group to hydrazone, oxime, and oxyacid were small when the grafting yield of acrolein was high.

    Amidoxime-group-containg adsorbents for metal ions synthesized by radiation-induced grafting (1985)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Amidoxime-group-containing fibrous adsorbents for metal ions were synthesized by radiation-induced grafting of acrylonitrile followed by amidoximation of cyano groups with hydroxylamine. The degree of amidoximation and the distribution of amidoxime groups in the fiber were follwed by means of electron probe X-ray microanalysis. The efficiency of adsorbing metal ions was increased by alkaline treatment of the adsorbent at high temperature for a short period before use. The order of adsorption for various bivalent metal ions was Hg 〉 Cu 〉 Ni 〉 Co 〉 Cd. From the distribution pattern of metal ions in the fibrous adsorbent, the adsorption was found to be controlled by the diffusion of the solution containing metal ions inside the adsorbent. It was found that confining amidoxime groups superficially and making short chain length of grafts were effective to obtain a high degree of adsorption.
