DB34/T 310014-2023 The determination of chlorine gas in fixed pollution sources using ion chromatography

Scope

This document describes the principles, interferences and eliminations, reagents and materials, instruments and equipment, samples, analysis steps, result calculation and presentation, accuracy, quality assurance, and quality control of the ion chromatography method for determining gaseous free chlorine in the organized emissions of waste gas from fixed pollution sources. This document is applicable to the determination of chlorine in the organized emissions of waste gas from fixed pollution sources. When the sample volume is 50.0 mL and the injection volume is 25 μL, the minimum detectable amount of chlorine is 1.80 μg. When the sampling volume is 60 L (standard state), the method's detection limit is 0.03 mg/m3 and the determination limit is 0.12 mg/m3.
