1. Scope |
1.1 This test method covers the determination of the organic halides in water in concentrations from 5 to 1000 [mu]g/L. Higher halide concentrations may be determined by making an appropriate dilution. 1.2 This test method is applicable only for those organic halides that can be adsorbed by granular activated carbon (GAC). 2,3,4 1.3 This test method is applicable to samples whose inorganic halide concentration does not exceed the organic halide concentration by more than 20000 times. Chloride ion may be determined by Test Methods D512. See Section 6. 1.4 This test method was used successfully with several waters (see 14.3). It is the user's responsibility to ensure the validity of this test method for waters of untested matrices. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
