Copper ores and tailings - Chemical analysis methods Part 6. Determination of cadmium content Flame atomic absorption spectrometry1 ScopeYS/T 1115 provisions of this part of the copper ore and tailings Determination of cadmium content. This section applies to the determination of copper content in copper ore and tailings. The measurement range is 0.0005% ~ 0.010%.2 method summarySample with hydrochloric acid, nitric acid, hydrofluoric acid and perchloric acid decomposition. Salts with hydrochloric acid dissolved in dilute hydrochloric acid medium, atomic absorption spectrometer waves 228.8nm long, the use of air - acetylene flame, using subtraction background mode, measuring the absorbance of cadmium, with the working curve method for calculating the amount of cadmium.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 Standard cadmium storage solution Weigh 1.0000g metal cadmium (wCd ≥ 99.99%), placed in 400mL beaker, add 50mL of nitric acid (3.6), cover the table dish, heated until completely dissolved, boiled to remove nitrogen oxides, removed and cooled to room temperature, into a 1000mL volumetric flask, add Into 50mL nitric acid (3.6), diluted with water to the mark, mix well. 1mL of this solution contains 1mg of cadmium. 3.8 Cadmium standard solution Pipette 10.00mL standard solution of cadmium (3.7) In a 100mL volumetric flask, add 10mL hydrochloric acid (3.5), Dilute to the mark with water and mix well. 1 mL of this solution contains 100 μg of cadmium. 3.9 Cadmium standard solution Pipette 10.00mL cadmium standard solution (3.8) In a 100mL volumetric flask, add 10mL hydrochloric acid (3.5), water Dilute to the mark and mix well. 1 mL of this solution contains 10 μg of cadmium.4 instrumentsAtomic Absorption Spectrometer with cadmium 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 consistent, the characteristic concentration of cadmium should not exceed 0.025μg/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 ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of YS/T 1115.6-2016_English be delivered?Answer: Upon your order, we will start to translate YS/T 1115.6-2016_English as soon as possible, and keep you informed of the progress.
