Description:
Various methods for the determination of total organic halides (TOX) in groundwater and in waste oil samples have been evaluated. Of three inorganic halide species generation approaches and three inorganic halide determinative techniques evaluated for groundwater analyses, one combined approach using Schoeniger flask oxidation with colorimetric chloride determination was chosen for laboratory validation and method detection limit studies. Groundwater samples were also analyzed for TOX using neutron activation analysis. A method for analysis of oil samples which uses the sodium biphenyl reagent and a colorimetric chloride method was found to be unsatisfactory for the analysis of various oils spiked with PCBs due to interferences in the colorimetric determinative step which resulted in recoveries greater than 100%.
