ASTM D6414通过酸提取或潮湿氧化/冷蒸气原子吸收对煤和煤燃烧残留物中总汞的标准试验方法

ASTM D6414 Standard Test Methods for Total Mercury in Coal and Coal Combustion Residues by Acid Extraction or Wet Oxidation/Cold Vapor Atomic Absorption
ASTM D6414通过酸提取或潮湿氧化/冷蒸气原子吸收对煤和煤燃烧残留物中总汞的标准试验方法

The emission of mercury during coal combustion can be an environmental concern.
When representative test portions are analyzed according to one of these procedures, the total mercury is representative of concentrations in the sample.

1. Scope
1.1 These test methods cover procedures to determine the total mercury content in a sample of coal or coal combustion residue.
1.2 The values stated in SI units are regarded as the standard.
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.
