A fibrous grafted metal adsorbent with a piperazinyl-dithiocarbamate (PZ-DTC) group was synthesized by radiation-induced emulsion grafting of glycidyl methacrylate onto a polyethylene-coated polypropylene nonwoven fabric (PE/PP-NF) and subsequent three-step chemical modifications consisting of amination with N-(tert-butoxycarbonyl)piperazine (N-Bocpiperazine, NBPZ), deprotection of the Boc group with HCl, and dithiocarbamation with carbon disulfide (CS 2 ). By using the NBPZ reagent in the amination step, the self-cross-linking of piperazine (PZ) could be completely suppressed, unlike using the PZ reagent. Consequently, the PZ-DTC group density of the fibrous grafted metal adsorbent synthesized through NBPZ attained 2.122 mmol-PZ-DTC/g-adsorbent, which was approximately 6 times higher than that of the metal adsorbent synthesized through PZ. The fibrous grafted metal adsorbent with the PZ-DTC group selectively adsorbed heavy metal ions over light metal ions. Furthermore, it exhibited high adsorption capacity, particularly for Cu 2+ . The Cu 2+ adsorption capacity was determined to be 1.903 mmol-Cu 2+ /g-adsorbent by a batchwise adsorption test using a single-metal-ion aqueous solution at pH 6. The order of metal ion selectivity of the fibrous grafted metal adsorbent with the PZ-DTC group was

“…To introduce the groups onto PE/PP- g -GMA, the PE/PP- g -GMA fabrics were treated with 0.5 M disodium iminodiacetate (IDA) in a 1:1 v/v ethanol/water solution at 70 °C for 24 h [20]. The resulting IDA-GMA-grafted PE/PP (PE/PP- g -GMA-IDA) fabric was washed with water and methanol to remove unreacted disodium iminodiacetate.…”

Development of a Simplified Radiation-Induced Emulsion Graft Polymerization Method and Its Application to the Fabrication of a Heavy Metal Adsorbent

A simplified radiation-induced emulsion graft polymerization (SREG) method is proposed. This method involves a convenient and easy degassing process of a monomer solution using a commercially available sealed glass jar. A loaded weight on the lid of the jar was used to control the jar’s internal pressure as the degassing of the monomer solution took place using a vacuum pump. The degassing method was highly reproducible, resulting from no bumping of the monomer solution. The initial grafting velocity was proportional to the absorbed doses of pre-irradiation between 5 and 20 kGy. This result indicates that dissolved oxygen was sufficiently eliminated from the monomer solution at such a level where the remaining oxygen had little effect on the grafting reaction at a dose of 5 kGy. The method was then applied to the fabrication of a heavy metal adsorbent that possessed a sufficient adsorption capacity of Co(II) ions. The SREG method is applicable to the fabrication of a wide variety of functional graft polymers because high-dose-rate gamma-ray radiation and expensive experimental equipment are not necessary.

“…Glycidyl methacrylate (GMA) contains epoxy groups that can easily react with -COOH, -OH, and -NH2 [3,4]. The ring-open reaction of the epoxy groups in GMA polymers can not only be applied in gene therapy [5], enzyme immobilization [6], but also be employed to prepare chelating materials and adsorbents [7] for the solid phase extraction, separation, and purification of biological macromolecules [8], environmental treatment, and chromatographic fixation [9]. Therefore, it will fulfill the high-valued utilization of wool through grafting PGMA branches onto the wool surface.…”

To explore suitable synthesis parameters of efficient graft copolymerization on wool, the disulfide bonds in wool chains were reduced to sulfhydryl groups by the treatment of thioglycolic acid to wool, and then wool-g-poly(glycidyl methacrylate) was prepared by graft copolymerization of wool with glycidyl methacrylate by building a redox system between sulfhydryl groups and ammonium persulfate. The wool-g-poly(glycidyl methacrylate) was characterized by the analyses of Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric and x-ray diffraction. Influences of molar concentrations of monomer and initiator as well as reaction temperature on grafting ratios were investigated. The experimental results showed that the sulfhydryl groups/ammonium persulfate redox system built could effectively initiate graft polymerization of lipophilic glycidyl methacrylate on the wool surface in an aqueous medium. The suitable process parameters of graft copolymerization were: 0.6 mmol/L molar concentration of glycidyl methacrylate, 3.0 mmol/L molar concentration of ammonium persulfate, and reaction temperature of 50 ℃. At the suitable parameters, the grafting ratio of wool-g-poly(glycidyl methacrylate) showed a maximum value of 195.8 %, indicating an efficient graft copolymerization was achieved. The copolymerization could reduce the degree of crystallinity of wool. The wool-g-poly(glycidyl methacrylate) had higher thermal stability than raw wool at a temperature of below 406 ℃ by performing the thermogravimetric analysis. Based on the results, we successfully built new sulfhydryl groups on the wool/ammonium persulfate redox system, prepared the wool-g-poly(glycidyl methacrylate), and this work will lay an important foundation for the application of wool-g-poly(glycidyl methacrylate) in the textile field.
