Introduction
1. Background of standard formulation and analysis of technological evolution
The wide application of chemical fibers in the fields of textiles, materials science, etc. has put forward higher requirements for the determination of antioxidant activity. This standard is based on the internationally advanced antioxidant activity detection technology and is formulated in combination with the actual domestic situation, aiming to provide a unified technical specification for the quality assessment of chemical fibers.
2. Comparison table of standard frameworks
| Standard dimensions | GB/T45178-2024 | Internationally accepted standard | Main improvements |
|---|---|---|---|
| Scope of application | Chemical fibers modified with antioxidant active ingredients | Applicable to all types of chemical fibers | Focus more on functional chemical fibers |
| Detection methods | DPPH method and ABTS method | Single DPPH method | Add ABTS method to improve detection accuracy |
| Reagent requirements | Strictly regulate the purity and preparation methods of reagents | General reagent requirements | Refine the reagent preparation process |
3. Recommendations for standard implementation
Case analysis: Practical application of DPPH method and ABTS method
- DPPH method is suitable for rapid determination and small batch sample testing.
- ABTS method is suitable for quality control of large enterprises with high precision requirements.
- It is recommended that enterprises choose appropriate methods according to actual needs and combine with automated equipment to improve detection efficiency.
