ASTM E1754-17a
(Test Method)Standard Test Method for Determination of Low Levels of Water in Liquid Chlorine By Infrared Spectrophotometry
Standard Test Method for Determination of Low Levels of Water in Liquid Chlorine By Infrared Spectrophotometry
SIGNIFICANCE AND USE
4.1 Trace amounts of water may be detrimental to the use of chlorine in some applications. The amount of water in the chlorine must be known to prevent problems during its use.
SCOPE
1.1 This test method covers the determination of the content of water in liquid chlorine in the concentration range of 0.5 to 15 mg/kg (ppm).
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.3 Review the current Safety Data Sheets (SDS) for detailed information concerning toxicity, first aid procedures, and safety precautions.
1.4 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. See Section 7 for specific hazards statements.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Summary of Test Method
3.1 A sample of liquid chlorine is introduced into a special infrared cell and maintained as a liquid under its own pressure. A
spectrometer scans from 400 to 4400 wavenumbers of the infrared transmission spectrum of liquid chlorine. This spectrum is then
ratioed to one obtained of the nitrogen-filled infrared cell previously. The ratioed spectrum is converted to absorbance, and the net
absorbance of the water band at 1596 wavenumbers, relative to a reference at 1663 wavenumbers, is determined. The amount of
water corresponding to this net absorbance is determined from a calibration curve prepared from the infrared absorbances of
standards that contain known concentrations of water in liquid chlorine.
