22、5ISO 17211:2015(E)IntroductionSince it is estimated that selenium is exhausted from stationary sources like coal combustion plants, the investigation of the emission amounts of selenium from the stationary source is increasingly important for preventing a potential risk.This International Standard d
23、escribes a method for the sampling and determination of selenium compounds in a flue gas passing through ducts or chimneys. Selenium compounds generally exist both in vapour phase and in solid phase in flue gases, this method allows the determination of both gaseous and particulate selenium concentr
24、ations in flue gases.vi ISO 2015 All rights reservedBS ISO 17211:2015Stationary source emissions Sampling and determination of selenium compounds in flue gas1 ScopeThis International Standard describes the method for the sampling and determination of selenium compounds in both vapour phase and solid
25、 phase that are entrained in flue gases carried in stacks or ducts. The selenium content in flue gas is expressed as a mass concentration of elemental selenium in the stack gas.Particulate and gaseous selenium compounds are captured by a filter and an absorber solution, respectively. The total conce
26、ntration of selenium compounds in flue gas is expressed as the sum of both concentrations.The concentrations of selenium in both samples are determined using inductively coupled plasma optical emission spectrometry (ICP-OES), inductively coupled plasma mass spectrometry (ICP-MS) or graphite furnace
27、atomic absorption spectrometry (GFAAS). Hydride generation (HG) techniques coupled to atomic spectrometry can also be used such as HG-AAS, HG-AFS (atomic fluorescence spectrometry), HG-ICP-OES and HG-ICP-MS.The detection limit for gaseous selenium compounds is 0,3 g/m3using HG-ICP-MS at a sampling v
28、olume of 0,12 m3. The detection limit for particulate selenium compounds is 0,001 2 g/m3using this technique at a sampling volume of 2,0 m3.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
