Introduction
1. Background and significance of standard formulation
With the development of artificial leather and synthetic leather industry, azodicarbonamide, as an important chemical additive, is widely used in the production process. However, the determination of its content is of great significance for product quality control and environmental protection. The formulation of this standard fills the gap in the industry and provides a technical basis for ensuring product safety and environmental protection.
2. Comparative analysis of standard frameworks
| Standard dimensions | GB/T 44501—2024 | International similar standards | Comparative analysis |
|---|---|---|---|
| Scope of application | Artificial leather, synthetic leather and base fabric | Widely used in plastic products and textile materials | Domestic standards focus more on specific materials |
| Determination method | High performance liquid chromatography (HPLC) | Gas chromatography (GC) and mass spectrometry (MS) | HPLC is more selective and suitable for complex matrices |
| Detection limit | 10.0 mg/kg | Usually 5.0-20.0 mg/kg | Domestic standards are more stringent |
3. Practical application case
A leather-making enterprise adopted this standard to determine the content of azodicarbonamide in its products. The results showed that the product with a content of 15 mg/kg was accurately determined by HPLC. This method significantly improved the detection efficiency and provided a reliable basis for the company's product quality control.
