1 Scope

YS/T 1115 provisions of this part of the copper ore and tailings Determination of manganese content. This section applies to the determination of manganese content of copper ore and tailings. The measurement range is from 0.0050% to 0.50%.

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 At 279.5 nm, the air-acetylene flame was used to measure the absorbance of manganese and the manganese content was calculated using the working curve method.

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 Hydrochloric acid (1 1). 3.6 manganese standard stock solution Weigh 1.0000g of metal manganese (wMn ≥ 99.99%) placed in 250mL beaker, add 20mL hydrochloric acid (3.5) heated to dissolve completely, removed and cooled to room temperature, transferred to a 1000mL volumetric flask, was added 80mL hydrochloric acid (3.5), diluted with water until engraved Degree, mix well. 1 mL of this solution contains 1 mg of manganese. 3.7 manganese standard solution Pipette 10.00mL manganese standard stock solution (3.6) placed in 100mL volumetric flask, add 10mL hydrochloric acid (3.5), diluted with water to the mark, mix well. 1 mL of this solution contains 100 μg manganese.

4 instruments

Atomic absorption spectrometer, with manganese 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 and the test solution is basically the same, the characteristic concentration of manganese should not exceed 0.040μg/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 0.80. ......
