“…Characteristic absorption peak of CMC and GA appeared at 3500 cm -1 for the hydroxyl groups (Silverstein and Webster 1998;Senna et al 2001). In the spectrum of unirradiated spectra there are bands at 2915, 1463 and 719 cm -1 , responsible for deformed vibration of CHgroups (Ibrahim et al 2006) as shown in these figures. In these figures there was new bands around 1700 cm -1 due to C=O absorption characteristic of COOH group of 100% CMC and 80% CMC in the unirradiated and irradiated spectra.…”

Polymer blends based on carboxymethylcellulose (CMC) and gum arabic (GA) were prepared by solution casting method. Glycerol was added to the polymer blend solution as a plasticizer with different ratios (2⋅5, 5, 10 and 20%). Then, the plasticized blends were exposed to gamma irradiation at different doses (5, 10 and 20 kGy). The physical properties of the plasticized polymer blends were investigated in terms of gel fraction (%) and swelling percent (%). Thermal properties were investigated by TGA. Also, the structure of the plasticized polymer blends was characterized by Fourier transform infrared spectroscopy. Scanning electron microscope was investigated in order to examine the compatibility between two polymers in the blend and also between polymer blend and plasticizer. The prepared plasticized polymer blends were used as an adsorbent for different dyestuffs. The sorption of dyestuffs by the plasticized polymer blend was determined by a method based on spectroscopic analysis. The results showed that the plasticized polymer blend has a high affinity for basic, acid, reactive and direct dyes. The obtained results showed that using glycerol as plasticizer improved the swellability of polymer blend and also the dye uptake (%).

A modified polyethylene coated polypropylene (PE‐coated‐PP) non‐woven fabric was prepared by surface coating with a constant layer of thickness (25 μm) of a mixture of an aqueous solution of carboxymethyl cellulose (CMC) and different concentrations of acrylic acid (AAc). Radiation curing of the coated layer was accomplished by electron beam irradiation with a constant dose of 30 kGy. The value of coating percent was calculated in terms of difference in weight. Properties related to hydrophilicty, such as swelling and water uptake %, were investigated by difference in weight of dry and wet samples after several washing cycles. Weight loss, before and after several washing cycles, was monitored. The effect of AAc concentration on the weight loss % of the modified fabric was studied. Moreover, the swelling in different solvents, dilute acid and base, was investigated. The structure of the modified fabric was characterized by Fourier transform infrared spectroscopy and scanning electron microscope in order to examine the compatibility between the coated layer and fabric. Mechanical properties in terms of tensile strength and elongation at break were studied. The efficiency of the uptake of this modified fabric toward basic, reactive dyes, and metal ions such as Cu2+, Ni2+, and Co2+ was measured by UV spectrophotometer and energy dispersive X‐ray. The results obtained show good efficiency of these modified fabrics toward heavy metal ions and dyes. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

Nowadays, radiation grafting polymer adsorbents have been widely developed due to their advantages, such as low operating cost, high efficiency. In this research, glycidyl methacrylate monomers by simultaneous irradiation of gamma-ray with a dose of 20 kGy were grafted on polypropylene polymer fibers. The grafted polymer was then modified using different amino groups and tested for adsorption of cobalt ions in an aqueous solution. Finally, modified polymer adsorbent with the high efficiency for cobalt ions adsorption was synthesized and tested for further investigation. Different modes of cobalt ions adsorption were tested in other adsorption conditions, including adsorption contact time, pH, different amounts of adsorbent mass, and different concentrations of cobalt ions solution. The adsorbent structure was characterized with FT-IR, and SEM techniques and illustrated having an efficient grafting percentage and adsorption capability for cobalt removing by batch experiments. The optimum conditions were obtained by a central composite design as follows: adsorbent mass = 0.07 g, initial concentration = 40 mg/L, time = 182 min, and pH = 4.5 with ethylenediamine as a modified monomer and high amination percentage. The features such as inexpensive adsorbent, easy to prepare, high efficiency, and stability allow the radiated-induced grafted adsorbent to constitute one of promising materials for heavy metals remediation.
