GB/T 14506.18-2010 Methods for chemical analysis of silicate rocks—Part 18:Determination of copper content
Abstract
This part of GB/T 14506 specifies the method for determining the amount of copper in silicate rocks.
This part is applicable to the determination of copper in silicate rocks, as well as in soil and aquatic sediments.
Measurement range: The copper content measured by the sodium hydroxide-ammonium chloride base solution method using a square-wave polarograph is more than 4 μg/g. The copper content measured by the oscillopolarographic derivative part is more than 10 μg/g. The copper content measured by the potassium thiocyanate-ethylenediamine-sodium sulfite base solution polarography method is 5 μg/g to 125 μg/g. The copper content measured by the flame atomic absorption spectrometry method is 5 μg/g to 500 μg/g.
