1 Scope
This part of YS/T 1050 specifies the method for the determination of thallium in lead and antimony concentrates.
This part is suitable for the determination of thallium in lead antimony concentrate, the method of determination is 0.0001% ~ 0.010%; Method 2 determination range
0.010% to 0.10%.
2 Method 1 Inductively Coupled Plasma Mass Spectrometry
2.1 Method Summary
Samples of hydrochloric acid, nitric acid, hydrofluoric acid, perchloric acid dissolved, hydrogen bromide volatile in addition to antimony. To iridium as the internal standard, in the hydrochloric acid medium, with the inductance coupling
Determination of Thallium by Plasma Mass Spectrometry.
2.2 Reagents
Unless otherwise stated, only reagents and primary water identified as excellent grade were used in the analysis.
2.2.1 Hydrochloric acid (ρ1.19g/mL).
2.2.2 nitric acid (ρ1.42g/mL).
2.2.3 Hydrofluoric acid (ρ1.15g/mL).
2.2.4 perchloric acid (ρ1.67g/mL).
2.2.5 hydrobromic acid (ρ1.49g/mL).
2.2.6 Thallium standard storage solution. Weigh 0.1000g metal thallium (wTl ≥ 99.99%) in 100mL beaker, add 50mL hydrochloric acid
(2.2.1) dissolved, into the 1000mL volumetric flask, diluted with water to the mark, mix. This solution 1mL thallium containing 100μg.
2.2.7 Thallium standard solution A. Remove 10.00mL thallium standard storage solution (2.2.6) In a 100mL volumetric flask, add 5mL hydrochloric acid
(
