Full Description

This article describes current methods for measuring organic halide including: carbon adsorption; the minicolumn method with resin as the adsorbent; extractable organic chlorine (EOCl); flash vacuum evaporation; neutron activation followed by gamma ray spectroscopy; and ion chromatographic analysis. Methods for analysis of purgeable organic halides (POX) and nonpurgeable organic halides (NPOX) are discussed. The measurement of disinfection by-products, including trihalomethanes (THMs); the use of total organic halide (TOX) as a surrogate for specific chemicals; sample stability; and availability and cost of TOX, POX, THM, and halogen-containing volatile organic chemical analyses are also addressed. Criteria for the selection of an analytical approach are examined. Includes 39 references, tables, figures.
