The as-obtained products were well characterized by XRD, SEM, TEM (HRTEM), SAED and N2 adsorption–desorption measurement. It was shown that the length and diameter of these alumina microfibers are about 10 μm and 300–500 nm, respectively. All these alumina microfibers prepared by the PEG templates with different molecular weight have the different high surface area but nearly the same pore diameter about 3.5 nm. The calcination experimental result shows that the mesoporosity of these alumina microfibers can be maintained even at 1373 K. On the other hand, the higher selective catalytic reduction (SCR) of NO effectiveness present that the as-obtained mesoporous alumina have stronger adsorption property because of its high surface area.

The effects of reaction parameters (reaction solvent, molar ratio of reagents, reaction temperature and reaction time) on the functional group capacity of PS-TETA resin were monitored to specify the best synthesis conditions. The functional group capacity and conversion percentage of functional group of PS-TETA prepared under the optimum condition were 2.13 mmol FG/g and 49.79%, respectively. The structure of PS-TETA was confirmed by elemental analysis and infrared spectra. The optimization of experimental conditions and parameters including pH, contact time, initial metal ion concentration for the removal of heavy metals were investigated. The maximum adsorption capacities of the resin for Hg(II), Cd(II) and Pb(II) evaluated from the Langmuir model were 344.8, 212.8 and 147.1 mg/g, respectively. Desorption studies revealed that Hg(II), Cd(II) and Pb(II) can be easily removed from PS-TETA by altering the pH values of the solution using HCl, which indicate that PS-TETA is a promising adsorbent for heavy metals removal from aqueous medium.

Langues : Anglais (eng) Mots-clés : Poly (methacrylic acid) hydrogel Structural properties Swelling kinetics Index. décimale : 660 Résumé : Poly(methacrylic acid) hydrogels were synthesized. The effects of the synthesis parameters: the neutralization degree of methacrylic acid and the concentrations of monomer, crosslinker and initiator on the xerogels structural properties: the xerogel density (ρxg), the number average molar mass between the network crosslinks (Mc), the crosslink degree (ρc), the number of elastically effective chains totally induced in a perfect network per unit volume (Ve), the distance between the macromolecular chains (ξ) and the equilibrium swelling degree (SDeq) and the swelling kinetics was investigated. As the concentrations of crosslinker, monomer and initiator increase, the value of ρxg, ρc and Ve increases and decreases the value of Mc, ξ and SDeq. With the increase in the neutralization degree of methacrylic acid, the values of ρxg, Mc, ξ, SDeq increase, while the ρc and Ve decrease. The xerogels structural properties, SDeq and swelling kinetic parameters are mainly in power law form functional relationships with the synthesis parameters as well as with the xerogels crosslinking degree.

Results show that these chemical characteristics can affect the degree of treatment in terms of COD and TOC removals. While aromatics exhibited a fast and great reduction in the COD by the conventional Fenton process, aliphatic compounds, apart from acetic acid, required the presence of UV light to enhance treatment results. EDTA and oxalic acid responded very positively to UV irradiation in both COD removal and mineralization, reaching the highest values showed by aromatics; and results depended on the intensity of the UV light applied. Phenol and 4-nitrophenol responded favourably to UV irradiation in terms of mineralization and slightly in COD removal. Reductions in the COD were almost total (95.99%), while only an 80% of reduction in the TOC was achieved, for the best photo-Fenton treatment of oxalic acid, phenol and nitrophenol. 60% COD and 40% TOC removals were achieved correspondingly in the case of EDTA. Acetic acid showed almost no mineralization and low COD removal (≈20%) when treated by a conventional Fenton process; and did not enhanced results when assisting the treatment with UV light. Photo-regeneration of ferrous ion and photo-decarboxylation of iron carboxylates are assessed in the framework of these results.

Langues : Anglais (eng) Mots-clés : Fennel biomass Regeneration Biosorption Desorption Breakthrough capacity Index. décimale : 660 Résumé : This work presents the biosorption potential of Fennel biomass for the effective removal of Cd(II) ions. The biosorption was maximum (92%) at pH 4.3. Maximum biosorption capacities of Cd(II) at 30, 40 and 50 °C temperatures were 21, 24 and 30 mg/g, respectively. The biosorption of Cd(II) was concentration dependent and increases from 0.49 to 9.3 mg/g with increase in concentration from 5 to 100 mg/L. Biosorption follows Freundlich isotherm at 50 °C. Mean free energies at different temperatures were in between 7.1 and 11.95 kJ/mol indicating chemical nature of biosorption process. Kinetics studies showed that pseudo-second-order kinetics model was applicable to the data. The process was endothermic and spontaneous, the spontaneity of the process increases with increase in temperature. Regeneration studies showed a decrease in the recovery of Cd(II) from 99.8% to 41.7% in five consecutive cycles. 80% of the Cd(II) in single and multi-metal systems was recovered in 10 mL. Breakthrough and exhaustive capacities of Cd(II) in single metal system were 10 and 40 mg/g. For multi-metal systems in double distilled water the breakthrough and exhaustive capacities of Cd(II) were 2 and 12 mg/g. In saline solution the breakthrough and exhaustive capacities of Cd(II) were 0.8 and 4 mg/g.
