Methods for chemical analysis of tin concentrates
Part 17. Determination of mercury content
Atomic fluorescence spectrometry
1 Scope
GB/T 1819 provisions of this part of the determination of mercury content in tin concentrate.
This section applies to the determination of mercury content tin concentrate. Measuring range. 0.00010% ~ 0.10%.
2 method summary
The sample is dissolved in hydrochloric acid and nitric acid. In a dilute hydrochloric acid medium, the ionic mercury is reduced to stannic mercury by stannous chloride and introduced into quartz by argon gas
In a furnace atomizer, the fluorescence intensity of mercury was measured on an atomic fluorescence spectrometer.
3 reagent
Unless otherwise specified, only reagents that are identified as analytically pure and secondary water are used in the analysis.
3.1 hydrochloric acid (ρ = 1.19g/mL), excellent grade pure.
3.2 Nitric acid (ρ = 1.42g/mL), excellent grade pure.
3.3 mixed acid (hydrochloric acid nitric acid water = 3 1 4).
3.4 Nitric acid (1 9).
3.5 Hydrochloric acid (1 19).
3.6 Stannous chloride solution (200g/L). Weigh 20g of stannous chloride (SnCl2 · 2H2O) in.200mL beaker, add 20mL hydrochloric acid
(3.1), slightly heated to dissolve completely, add 80mL water, mix well.
3.7 potassium permanganate solution (50g/L).
3.8 Mercury standard stock solution Weigh 0.1354g of mercury dichloride (wHgCl2 ≥ 99.99%) in 100mL beaker, add 5mL nitric acid
(3.2), slightly heated to dissolve completely, removed, cooled, transferred to a 1000mL volumetric flask, 10mL potassium permanganate solution (3.7), with nitric acid
(3.4) diluted to the mark, mix well. This solution 1 mL contains 100 μg mercury.
3.9 Mercury standard solution A. Pipette 10.00mL mercury standard stock solution (3.8) in 100mL volumetric flask, dilute to the mark with nitric acid (3.4)
Mix well. 1 mL of this solution contains 10 μg mercury.
3.10 Mercury standard solution B. Pipette 10.00mL mercury standard solution A (3.9) in 100mL volumetric flask, add 2mL nitric acid (3.2),
1mL potassium permanganate solution (3.7), diluted with water to the mark, mix well. 1 mL of this solution contains 1 μg mercury.
3.11 Mercury standard solution C. Pipette 10.00mL mercury standard solution B (3.10) in 100mL volumetric flask, add 2mL nitric acid (3.2),
1mL potassium permanganate solution (3.7), diluted with water to the mark, mix well. 1 mL of this solution contains 100 ng of mercury. Preparation with time.
4 instruments
