Copper ores and tailings - Chemical analysis methods Part 2. Determination of lead content Flame atomic absorption spectrometry1 ScopeYS/T 1115 provisions of this part of the copper ore and tailings Determination of lead content. This section applies to the determination of the amount of lead in copper ore and tailings. The measurement range is 0.050% ~ 1.00%.2 method summarySample 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 283.3 nm, the air-acetylene flame was used to measure the absorbance of lead and the amount of lead was calculated using the working curve method.3 reagentUnless 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). Nitric acid (1 1). 3.7 lead standard stock solution Weigh 1.0000g metal lead (wPb ≥ 99.99%) placed in 300mL beaker along the wall by adding 50mL Nitric acid (3.6), cover the surface of the dish heated to dissolve low temperature, heated to remove nitrogen oxide boiled, washed with water table, into the 1000mL volumetric flask In, add 50mL nitric acid (3.6) diluted with water to the mark, mix well. 1mL of this solution contains 1mg lead. 3.8 Lead standard solution Pipette 10.00mL lead standard stock solution (3.7) In a 100mL volumetric flask, add 5mL hydrochloric acid (3.1) with Dilute the water to the mark and mix well. 1 mL of this solution contains 100 μg lead.4 instrumentsAtomic Absorption Spectrometer, with lead hollow cathode lamp. In the best working conditions of the instrument, anyone who can meet the following indicators can be used. --- Characteristic Concentration. In the same solution as the measuring solution matrix, the characteristic concentration of lead should not exceed 0.075μg/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. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of YS/T 1115.2-2016_English be delivered?Answer: Upon your order, we will start to translate YS/T 1115.2-2016_English as soon as possible, and keep you informed of the progress.
