Mesoporous materials for the retention and separation of haloacetic acids

Chromatographia, 2002
Mesoporous silica-based materials have been synthesized and studied for applications in the environmental field. Haloacetic acids have been chosen as test compounds since they are byproducts of disinfection processes of water for human consumption. For this purpose mesoporous materials have been synthesized in acid, basic or neutral conditions.

Infrared study of α-haloacetic acids in solution

Vibrational Spectroscopy, 1996
Abstract Rotation of the XCH 2 , X 2 CH, or X 3 C group about the carbonyl group for haloacetic acids causes erratic ν(CO) and ν op (CO) 2 frequency behavior that appears to offset the inductive effect. The inductive effect causes both ν(CO) and ν op (CO) 2 to either increase or decrease in frequency, depending upon whether sigma electrons of ...

Haloacetic Acids in Canadian Lake Waters and Precipitation

Environmental Science & Technology, 2000
Haloacetic acids (HAAs) were measured in lake water and precipitation in distinct geographical areas of Canada with the objective of determining prevailing levels and source regions of these phytotoxins. This included surface water samples from the Great Lakes and four lakes in widely separated geographical areas of Canada.

Techniques and methods for the determination of haloacetic acids in potable water

Journal of Environmental Monitoring, 2000
Haloethanoic (haloacetic) acids (HAAs) are formed as disinfection byproducts (DBPs) during the chlorination of natural water to make it fit for consumption. Sundry analytical techniques have been applied in order to determine the concentrations of the HAAs in potable water supplies: gas chromatography (GC-MS, GC-ECD); capillary electrophoresis (CE ...

[Study advance on haloacetic acids in drinking water].

Wei sheng yan jiu = Journal of hygiene research, 2010
Haloacetic acids (HAAs) in drinking water have attracted more and more attention of researchers due to their higher potential combination of chlorine, their carcinogenic and mutagenic effects and higher carcinogenic. The formation mechanism, analytical methods, the effects of many factors on HAAs formation such as precursor types, chlorine doses, pH ...
