GB/T 14506.19-2010 Methods for chemical analysis of silicate rocks—Part 19:Determination of lead content
Abstract
This part of GB/T 14506 specifies the methods for determining the lead content in silicate rocks.
This part is applicable to the determination of lead content in silicate rocks, as well as the determination of lead content in soil and aquatic sediments. It is not applicable to gabbro with high iron and titanium content.
Determination range: Flame atomic absorption spectrophotometry, lead content from 5 μg/mL to 500 μg/mL. Polarographic method with hydrochloric acid-tartaric acid-potassium iodide buffer solution, lead content from 10 μg/mL to 250 μg/mL.
