Standard Test Method for
Total Carbon and Organic Carbon in Water by Ultraviolet, or
Persulfate Oxidation, or Both, and Infrared Detection1
This standard is issued under the fixed designation D 4839; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
a superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1.1 This test method covers the determination of total
carbon (TC), inorganic carbon (IC), and total organic carbon
(TOC) in water, wastewater, and seawater in the range from 0.1
mg/L to 4000 mg/L of carbon.
1.2 This test method was used successfully with a reagent
water spiked with sodium carbonate, acetic acid, and pyridine.
It is the user’s responsibility to ensure the validity of this test
method for waters of untested matrices.
1.3 This test method is applicable only to carbonaceous
matter in the sample that can be introduced into the reaction
zone. The syringe needle or injector opening size generally
limit the maximum size of particles that can be so introduced.
1.4 In addition to laboratory analyses, this test method may
be applied to stream monitoring.
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.
