(Test Method)Standard Test Method for Mercury in Liquid Chlorine
Standard Test Method for Mercury in Liquid Chlorine
SIGNIFICANCE AND USE
4.1 This test method was developed primarily for the determination of traces of mercury in chlorine produced by the mercury-cell process.
SCOPE
1.1 This test method2 covers the determination of mercury in liquid chlorine with a lower limit of detection of 0.1 μg/L.
1.2 Review the current Safety Data Sheet (SDS) for detailed information concerning toxicity, first-aid procedures, and safety precautions.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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. Specific precautionary statements are given in Sections 7, 6.3, 6.4, 6.5, and Note 2.
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 Liquid chlorine samples are taken in chilled glass flasks, then allowed to evaporate slowly to dryness. The mercury is left
in the residue. The residue is dissolved in dilute nitric acid and diluted to volume. The addition of nitric acid prevents any loss
of mercury from the aqueous solution on standing. For analysis, an aliquot of the acidic aqueous solution is boiled with excess
permanganate to remove interfering materials. The mercuric ions are then reduced to metallic mercury with stannous chloride. The
solution is aerated and the mercury, now in the air stream, is determined using an atomic absorption spectrophotometer.
