Carbonate radical (CO3-) is a powerful oxidant that is present in sunlit surface waters and in waters treated by advanced oxidation processes. The production of CO3- in aqueous solution through oxidation of carbonate anion by excited triplet states of arom ...
A pulse of chromated copper arsenate (CCA, a timber preservative) was applied in irrigation water to an undisturbed field soil in a laboratory column. Concentrations of various elements in the leachate from the column were measured during the experiment. A ...
The internal cycles of carbon, silica, nitrogen, and phosphorus in the South and North Basins of Lake Baikal were quantified in the frame of a multidisciplinary collaboration. Fluxes of particulate organic matter from the epilimnion to the deep water were ...
Wastewater containing mainly 5-amino-6-methyl-2-benzimidazolone (AMBI), used in the manufacture of dyes, was characterized as bio-recalcitrant by means of different biodegradability tests. In order to enhance the biodegradability of this important pollutan ...
Based on previous findings (Jans, U., Hoigne, J., 1998. Ozone Sci. Eng. 20, 67-87), the activity of activated carbon for the transformation of ozone into e OH radicals including the influence of operational parameters (carbon dose, ozone dose, carbon-type ...
The effect of different chemical parameters on photocatalytic inactivation of E. coli K12 is discussed. Illumination was produced by a solar lamp and suspended TiO2 P-25 Degussa was used as catalyst. Modifications of initial pH between 4.0 and 9.0 do not a ...
The current work examines the effects of model allochtonous (humic substances) and autochtonous (microbial polysac charides) natural organic matter (NOM) on Pb speciation and bioaccumulation. The results demonstrated that polysaccharides, in particular alg ...
Biotrickling filter (BTF) technology was applied for the treatment of waste gas containing a mixture of chlorobenzene and 1,2-dichlorobenzene. An adapted microbial community was immobilised on a structured packing material. The strategy followed was to rea ...
Potentially carcinogenic bromate forms during the ozonation of bromide-containing waters. Some water treatment facilities have had to use ammonia addition and pH depression to minimize bromate formation, but these processes may prove to be insufficient to ...
Bactericidal action of illuminated TiO2 on pure culture of Escherichia coli K 12 and bacterial consortium was studied. Photocatalytic E. coli inactivation rate was dependent on the biological parameters such as: physiological state, generation and initial ...
