Abstract:In this study, we aimed to identify the effect of agar proportion on the synthesized superabsorbent properties based on PVP (Polyvinyl pyrrolidone), poly (ethylene glycol) (PEG) and agar. In a first stage, the study of swelling and deswelling behavior of synthesized hydrogel was done. It was proved that agar acts as a crosslinking inhibitor since it competes with free radicals. The pH versus swelling time was studied. The polymer was characterized by Fourier transform infrared spectra analysis and X-ray Diffraction. The removal of Cu(II) from aqueous solution by the prepared PVP/PEG/agar hydrogel was studied. Also, the influences of pH and contact time were investigated throughout adsorption experiments. The maximum retention capacity was found to be 36.5 mg g -1 for the hydrogel containing 1% of agar. The kinetic parameters were calculated from the experimental data and it was shown that they fit well with pseudo-second-order kinetic model.

“…Irradiations of the glass samples were done at the Tunisian semi-industrial 60 Co gamma irradiation facility at the dose rate of about 2 kGy/h (Farah et al 2006). Dosimetry was done using Fricke and Ethanol-ChloroBenzene chemical dosimeters and the traceability was established with alanine/EPR dosimetry system in terms of absorbed dose to water traceable to Aérial Secondary Standard Dosimetry Laboratory (SSDL), Strasbourg-France (Aérial, 2011).…”

“…Some interruption may be planned, for example when the irradiation of the product is carried out in several cycles in order to achieve good dose distribution [1]. Other interruptions are unplanned due of the shutdown of the irradiator.…”
