Preconcentration and separation of haloacetic acids by ion chromatography

Journal of Chromatography A, 1999
A comparative study was made of the chromatographic behaviour of five haloacetic acids (mono-, dibromoacetic and mono-, di-, trichloroacetic acids). The techniques investigated included reversed-phase ion interaction chromatography with UV detection, suppressed and non-suppressed anion-exchange chromatography.

The Henry's Law Constants of the Haloacetic Acids

Journal of Atmospheric Chemistry, 1998
Henry's law constants K′H (mol kg-1 atm-1) have been measured between 278.15 K and 308.15 K for the following organic acids: CH2FCOOH (ln(K′H[298.15 K]) = 11.3 ± 0.2), CH2ClCOOH (11.59 ± 0.14), CH2BrCOOH (11.94 ± 0.21), CHF2COOH (10.32 ± 0.10), CHCl2COOH (11.69 ± 0.11), CHBr2COOH (12.33 ± 0.29), CBr3COOH (12.61 ± 0.21), and CClF2COOH (10.11 ± 0.12 ...

Determination of haloacetic acids by ion chromatography

Journal of Chromatography A, 1994
Two ion chromatography methods for the determination of haloacetic acids are described in this paper. The first method is based on anion-exchange separation with suppressed electrical conductivity detection. The second method is based on anion-exclusion separation with UV detection. Both methods are simple and fast.

Haloacetic Acids as Corrosion Inhibitors for Brass in Nitric Acid

Corrosion, 1982
The effect of chloro, dichloro, trichloro, bromo, and iodoacetic acids on corrosion of brass in dilute nitric acid has been studied using weight loss and polarization techniques. A significant retardation of the corrosion rate is observed in the inhibited nitric acid.

Comparison of Haloacetic Acids in the Environment of the Northern and Southern Hemispheres

Environmental Science & Technology, 2005
Haloacetic acids (HAAs) are a family of compounds whose environmental concentrations have been extensively studied, primarily in Europe. Depending on the compound, their sources are believed to be both natural and anthropogenic. To better understand possible sources and contribute to the knowledge of the global distribution of these compounds ...

Haloacetic acids content of fruit juices and soft drinks

Food Chemistry, 2015
Water used in a food factory is frequently disinfected with chlorine, which originates disinfection by-products: haloacetic acids (HAAs) make up the second most prevalent class of these products. In this paper we propose the first static HS-GC-MS method developed for direct HAA determination in beverages; the method has higher sensitivity, simplicity ...

Inhalation Exposure to Haloacetic Acids and Haloketones during Showering

Environmental Science & Technology, 2002
Inhalation exposure to haloacetic acids (HAAs) and haloketones (HKs) in contaminated drinking water occurs during showering. The size distribution of the aerosols generated by a shower was determined using an eight size-range particle counter, which measured particles from 0.1 to >2 microm.

Comparative effects of haloacetic acids in whole embryo culture

Teratology, 1996
A major class of disinfection by-products in drinking water are the haloacetic acids. Both dichloro- and trichloroacetic acids are teratogenic when administered to rats throughout organogenesis. However, there is little information regarding the developmental toxicity of other haloacetic acids.

Amino Acids as Precursors of Trihalomethane and Haloacetic Acid Formation During Chlorination

Archives of Environmental Contamination and Toxicology, 2008
Twenty amino acids were chlorinated and examined for the formation of trihalomethane (THM) and haloacetic acid (HAA). The amino acids exhibited a high Cl(2) demand (3.4-10 mg Cl(2) mg(-1) C) but low THM formation (
