Introduction
GB/T 38233—2019 Standard Interpretation: Determination of Lead and Zinc in Iron-containing Dust and Mud
| Standard Dimensions | Technical Requirements | Scope of Application | Detection Accuracy |
|---|---|---|---|
| ICP-AES Instrument | - Wavelength Resolution: ≤0.012 nm - Measuring Range: 600 nm to 1050 nm | Applicable to quantitative analysis of lead and zinc in iron-containing dust and mud samples | Repeatability Limit r = 0.0274m + 0.0339 (Lead) - Reproducibility Limit R = 0.5355m - 0.2975 (lead) |
| Sample preparation process | - Sample particle size: ≤100 μm - Decomposition steps: Combined use of hydrochloric acid, nitric acid, hydrofluoric acid and perchloric acid | Laboratory analysis environment, professional operators are required | Zinc content determination range: 0.004%~15% |
Implementation suggestions and precautions
Step optimization suggestions: - Ensure that the sample is fully mixed to avoid errors - Pay attention to high temperature protection during sample decomposition - Use high-purity reagents to ensure detection accuracy
Instrument calibration precautions: - Regularly check the wavelength accuracy and sensitivity of the ICP-AES equipment - Repeat the measurement at least twice when establishing the standard curve
