GB/T 14506.20-2010 Methods for chemical analysis of silicate rocks—Part 20:Determination of zinc content
Abstract
This part of GB/T 14506 specifies the method for determining the zinc content in silicate rocks.
This part is applicable to the determination of zinc content in silicate rocks, and is also applicable to the determination of zinc content in soil and aquatic sediments.
Determination range: Polarographic method with sodium hydroxide-ammonium chloride as the base solution, for zinc content above 25 μg/g. Polarographic method with ethylenediamine as the base solution, for zinc content between 20 μg/g and 2,000 μg/g. Flame atomic absorption spectrometry, for zinc content between 5 μg/g and 200 μg/g.
