FTIR evaluation of functional groups involved in the formation of haloacetic acids during the chlorination of raw water

Soil Chemical Insights Provided through Vibrational Spectroscopy

“…FTIR has been used to study the mechanisms of HA formation in archeological samples (Ascough et al, 2011), analyze HA-like fractions from dust macromolecules (Zhao and Peng, 2011), and evaluate water fouling and treatment (Howe et al, 2002;Kanokkantapong et al, 2006). The use of FTIR for analyzing composition and quality of composts, industrial organic wastes, and sewage sludge, and their effects on SOM quality as soil amendments or disposed wastes, is well established (Martínez et al, 2012;Smidt and Meissl, 2007) and has been used to monitor humification during composting (Jouraiphy et al, 2008;Smidt and Schwanninger, 2005) as well as discerning compost quality as a function of feedstock and method (Carballo et al, 2008a;Fialho et al, 2010).…”

Electrochemical and spectroscopic characteristics of dissolved organic matter in a forest soil profile

“…4). The functional groups were identified according to published results (Kanokkantapong et al, 2006;Huo et al, 2008). All spectra featured a broad band at 3390 cm −1 , which can be attributed to O-H stretching from the presence of alcohols and/or phenols, and N-H stretching from amines and/or amides.…”

Disinfection and DBPs removal in drinking water treatment: A perspective for a green technology

“…Nevertheless, usage of other disinfectants has also been observed to form DBPs and present regulations attempt to stabilize the hazards between microbial pathogens and DBPs. DBPs comprise the following (Weiner, 2012):  Halogenated organic compounds, such as THMs, haloacetic acids, haloketones, and other halogenated compounds that are produced firstly while chlorine or ozone (in the presence of bromide ion) are utilized as disinfectant (Bougeard et al, 2008;Xie et al, 2015;Ye et al, 2012;Kanokkantapong et al, 2006;Navalon et al, 2009;Aydin et al, 2012;Rincón et al, 2001).  Organic oxidation by-products, such as aldehydes, ketones, assimilable organic carbon, and biodegradable organic carbon.…”
