Texto completoWater pollution is currently a major concern from both health and environmental point of view. In order to solve this problem, efficient decontamination processes, economic and sustainable are constantly being developed and adsorption process remains a widely used method in the wastewater treatment. Many studies are devoted to the adsorption of cationic pollutants, but the development of suitable supports able to interact with the anionic contaminants is less discussed. The main objective of this work is to form two anionic adsorbents: the LDH (Layered Double Hydroxide) Mg/Al and two-line ferrihydrite. These adsorbents were associated with an alginate gel in order to produce composite materials that can be implemented in continuous reactors for the removal of anionic contaminants. The adsorption studies in batch reactor on LDH and ferrihydrite confirmed good removal efficiency for some anions. Ferrihydrite showed a higher adsorption capacity than LDH for the removal of inorganic anions. Increasing the Mg/Al ratio was favorable for the methyl orange (MO) adsorption, and an Mg/Al ratio of 3 (L3) was selected for the following work. Two protocols were evaluated for the integration of adsorbent into alginate gel: encapsulation and direct synthesis in the gel structure. The effect of crosslinking cation and the making of macroporosity were studied. The encapsulation of solids decreased slightly the adsorption ability of anions; however, the macroporosity counterbalances this negative effect of alginate gel. The MO adsorption studies with encapsulated beads showed that the increase of the bead size and the amount of solid in the beads were accompanied with a decrease in the adsorption capacity. The replacement of Ca2+ by Ba2+ strengthened the gel structure and improved the adsorption kinetics but decreased the adsorption capacity. The characterization of the support material prepared by direct synthesis in alginate gel showed a different structure from the expected materials (L3 or ferrihydrite), and therefore a different reactivity. The sorption mechanisms of various organic and inorganic anions were proposed for the studied adsorbents. The ferrihydrite/alginate beads prepared by encapsulation showed a good adsorption for all the anions used in this work, especially for inorganic anions (phosphate, chromate and arsenate); while those produced by direct synthesis in alginate gel removed only arsenate and phosphate essentially by a precipitation mechanism of the anions at the surface of the iron oxides and oxy-hydroxides. The sorption of MO in a continuous reactor showed that the increasing of the flow rate had a negative effect on sorption while higher initial concentration presented a favorable effect on the sorption, which is in accordance with results obtained in batch reactor. A desorption ratio of 30% for ferrihydrite/alginate macroporous beads (BPENFh-Ba) was observed in batch reactor with the possibility of reusing the adsorbent.This study confirms the performance and the possibility to use the composite materials of LDH or ferrihydrite in an alginate gel for the removal of anionic compounds contained in wastewater

Texto completoSeveral ubiquitous organic contaminants, some of which are increasing in the environnement, seem to possess thyroid-disrupting capacities. These effects are suspected to be the underlying causes of neurodevelopmental deficits in infants prenatally exposed to polychlorinated biphenyls. The objectives of this project were 1) to evaluate the effects of chronic exposure to environmental contaminants on circulating concentrations of thyroid hormones in pregnant women, newborns and adult Inuit as well as 2) to quantify and identify determinants of exposure to emerging contaminants in the Nunavik Inuit population in 2004. Overall, results from newborns and pregnant women do not demonstrate clear associations between thyroid hormone concentrations and exposure to some persistent organic pollutants. However, negative associations between polychlorinated biphenyl concentrations and circulating levels of thyroglobulin were observed in neonates. Furthermore, pentachlorophenol concentrations in pregnant women during their last trimester of pregnancy were negatively associated with umbilical cord free T4 concentrations in newborns. In adults, exposure to a complex mixture of chlorinated compounds was related to a reduction in total T3 and thyroglobulin concentrations. Moreover, plasma concentrations of emerging contaminants such as perfluorooctanesulfonate (PFOS) and polybrominated diphenyl ethers (PBDEs) were also associated with disruptions of thyroid parameters. In 2004, exposure levels of PFOS and PBDEs in Nunavik Inuit adults were lower compared to those observed in other North-American populations, but similar and higher respectively, to those reported among European populations. The increase of PFOS plasma concentrations with age as well as with fish and marine mammal consumption seems to indicate that this compound tends to persist and bioaccumulate in the food-web. Sources of exposure to PBDEs were not clearly identified in the framework of this study. However, traditional food consumption and Inuit lifestyle seem to protect against exposure to congener PBDE 47, one of the most prevalent in humans.
