“…This metal ion can penetrate the skin causing irritation, liver and kidney damage as well as a decrease in male sperm counts (Morales et al, 1999). AAS analysis of the eluant after passing the Cr 6+ containing water samples demonstrated that the CD-IL polymers were able to remove Cr 6+ with an absorption efficiency of up to 100%.…”

“…On the other hand, inorganic pollutants, particularly heavy metals such as lead, cadmium, mercury and silver, have been reported to be toxic and even lethal to the human body, especially the central nervous system (Morales et al, 1999). These metals have a great affinity for sulphur and hence attack the sulphur bonds of enzymes causing them to malfunction (Lewis et al, 2001;Morales et al, 1999).…”

The prevalence of toxic contaminants in water remains a huge challenge for water-supplying companies and municipalities. Both organic and inorganic (especially heavy metals) pollutants are often present in water distribution networks. The presence of these contaminants in drinking water poses a major risk to human health. Organic and inorganic pollutants often co-occur in drinking water networks. However, at present there is no water treatment intervention that simultaneously removes both organic and inorganic pollutants from water to desirable levels. In our laboratories, recent studies have shown that both functionalised and un-functionalised cyclodextrin (CD) polymers are capable of removing organic pollutants from water, with the functionalised CD polymers showing an enhanced absorption capability. Ionic liquids (ILs), on the other hand, have been reported to absorb heavy metals from aqueous media. In this paper, we report on the synthesis of several cyclodextrin-ionic liquid (CD-IL) polymers, a dual system capable of removing both organic and inorganic pollutants from water. This system has been tested and has proved to possess excellent capabilities for the removal of model pollutants such as p-nitrophenol (PNP), 2,4,6-trichlorophenol (TCP) and chromium (Cr 6+ ) from aqueous media.

“…Inorganic pollutants include dissolved gases (e. g. oxygen, carbon dioxide, nitrogen and radon), heavy metals (e. g. Hg 2+ , Cd 2+ , Cr 6+ ) and anions such as fluorides (F¯), nitrates (NO 3¯) and cyanides (CN¯). These contaminants also pose health risks to living organisms because they bioaccumulate in the body resulting in chronic health effects (Morales et al, 1999). Inorganic contaminants are not biodegradable; hence they can typically poison the food chains of living organisms (waterborne, 2006).…”

“…Além dos graves problemas de saúde pública e degradação dos recursos locais, a poluição por esgotos domésticos está causando em escala mundial problemas de eutrofização e depleção de oxigênio nas águas costeiras. Isto se deve a presença de elevadas quantidades de nitrogênio e fósforo que causam aumento exponencial da produção primária local (Weber, 1992;Morales et al, 1999;Braga et al, 2000;Montone, 2006).…”
