1 Scope

This part of GB/T 7739 specifies the determination of lead, zinc, antimony and cadmium in gold concentrate by inductively coupled plasma atomic emission spectrometry. A method of the amount of chromium, arsenic and mercury. This section applies to the determination of lead, zinc, antimony, cadmium, chromium, arsenic and mercury in gold concentrates. The measurement range of each element is shown in Table 1. Table 1 Measurement range Element measurement range /% Element measurement range /% Lead 0.0050~5.00 Cadmium 0.0050~2.00 Zinc 0.0050~5.00 Chromium 0.010~2.00 Arsenic 0.0050~5.00 Mercury 0.0050~2.00 铋0.0050~2.00

2 Method summary

The sample is dissolved in hydrochloric acid or nitric acid (measurement of lead, zinc, antimony, cadmium, arsenic and mercury) or dissolved in sulfur-phosphorus mixed acid (determination of chromium) in dilute nitric acid medium In the selected condition of the inductively coupled plasma atomic emission spectrometer, the spectral intensity of each element in the test solution is determined, and the standard solution is used. As an internal standard, the amount of lead, zinc, antimony, cadmium, chromium, arsenic and mercury is calculated according to the standard curve internal standard method.

3 reagents

Analytically pure reagents and secondary deionized water were used in the analysis unless otherwise stated. 3.1 Nitric acid (ρ = 1.42 g/mL). 3.2 Hydrochloric acid (ρ=1.19g/mL). 3.3 Perchloric acid (ρ = 1.76 g/mL). 3.4 Sulfuric acid (ρ=1.84g/mL). 3.5 Phosphoric acid (ρ = 1.87 g/mL). 3.6 Hydrofluoric acid (ρ=1.14g/mL). 3.7 Tartaric acid solution (200g/L). ......
