1 Scope

YS/T 1115 provisions of this part of the copper ore and tailings Determination of nickel content. This section applies to the determination of nickel content in copper ore and tailings. The measurement range is from 0.0050% to 0.050%.

2 method summary

Sample with hydrochloric acid, nitric acid, hydrofluoric acid and perchloric acid decomposition. Hydrochloric acid dissolves salts in dilute hydrochloric acid medium at atomic absorption spectrometer wavelength 232.0nm, the use of air - acetylene flame, using subtraction of background mode, measuring the absorbance of nickel, nickel curve calculation of the amount of work.

3 reagent

Unless otherwise noted, only reagents identified as analytical grade were used in the analysis, all of which used distilled or deionized water or equivalent purity Water. 3.1 Hydrochloric acid (p = 1.19 g/mL). 3.2 Nitric acid (p = 1.42 g/mL). Hydrofluoric acid (ρ = 1.15 g/mL). 3.4 Perchloric acid (ρ = 1.67g/mL). 3.5 Nitric acid (1 1). 3.6 Nickel standard stock solution Weigh 0.5000g of metallic nickel (wNi ≥ 99.99%) placed in 250mL beaker, with 20mL of nitric acid (3.5) Cover the table low temperature heating to dissolve completely, boil away the nitrogen oxide, remove and cool to room temperature, transferred to 500mL volumetric flask, add 25mL nitric acid (3.5), diluted with water to the mark, mix well. 1 mL of this solution contains 1 mg of nickel. 3.7 Nickel standard solution Pipette 10.00mL nickel standard stock solution (3.6) into 100mL volumetric flask, add 5mL hydrochloric acid (3.1), Dilute to the mark with water and mix well. This solution 1 mL contains 100 μg of nickel.

4 instruments

Atomic absorption spectrometer with nickel hollow cathode lamp. Under the instrument working conditions, any atomic absorption spectrometer that can achieve the following indexes can be used. --- Characteristic concentration In the solution with the test solution is basically the same, the characteristic concentration of nickel should not exceed 0.050μg/mL; --- Precision. With the highest concentration of standard solution measured 10 times the absorbance, the standard deviation should not exceed 1.0% of the average absorbance; Measure the absorbance 10 times with the lowest concentration of the standard solution (not a "zero" standard solution) with a standard deviation of no more than the highest concentration Standard solution 0.5% of the average absorbance; --- The working curve of the linear. The working curve according to the concentration is divided into 5 segments, the highest segment of the absorbance difference and the lowest segment of the absorbance difference The ratio should not be less than 0.85.
