A two-block full-factorial matrix was designed to satistically evaluate the influence of bromide ion on the formation and speciation of haloacetic acids (HAAs) during chlorination and the effects of independent varables, including pH, reaction time,

Total organic halide (TOX) analyzers are commonly used to measure the amount of dissolved halogenated organic byproducts in disinfected waters. Because of the lack of information on the identity of disinfection byproducts, rigorous testing of the dis

Les halogenures organiques peuvent etre utilises comme indicateurs de la qualite de l'eau, fournissant une mesure directe de la formation de sous-produits de la desinfection de l'eau et parfois une mesure indirecte de polluants organiques particulier

The influence of bromide ion on the formation of nonpurgeable organic bromine and nonpurgeable organic chlorine was not studied previously because no analytical technique existed that could separately measure total organic chlorine and total organic

Organic halides are generally suspected of causing adverse health effects. For this reason, it is important to know of their presence in water that is intended for eventual human consumption. Only about 25 percent of the organic halides in chlorinate

Methodology is presented for the concentration, detection and measurement of vinyl chloride (VC) in water at a maximum sensitivity of 0.1 mug/1 by gas chromatography, using the halogen specific microcoulometric titration detector. The methodology eli

The use of 15% ethyl ether/hexane as the extracting solvent for BIS(2‐chloro‐)ethers in aqueous samples is evaluated using the p‐value approach to liquid‐liquid extraction. The evaluation supports the choice of solvent and largely accounts fo

Methyl mercury is extracted as the bromide salt from fish and sediment and as the chloride salt from water samples. All extracts are treated with a common cleanup procedure that results in the conversion of methyl mercury to the iodide salt for elect
