Introduction
Interpretation of the GB/T 34157-2017 Standard for High-efficiency Haloxyfop-p-ethyl Technical Material
Background and Significance of the Standard
GB/T 34157-2017 High-efficiency Haloxyfop-p-ethyl Technical Material is a standard proposed by the China Petroleum and Chemical Industry Federation and managed by the National Technical Committee for Pesticide Standardization. This standard specifies the requirements, test methods, safe storage and transportation requirements for high-efficiency Haloxyfop-p-ethyl technical material, and is applicable to the production and trade of high-efficiency Haloxyfop-p-ethyl.
Comparative Analysis of Technical Indicators
| Project | Indicator Requirements | Detection Method |
|---|---|---|
| Mass fraction of haloxyfop-ethyl/% | 95.0 | Liquid chromatography method |
| Acetone insoluble matter/% | 0.3 | GB/T 19138 |
| Water/% | 0.5 | Karl Fischer method |
| Acidity (in terms of H2SO4)/% | 0.1 | Indicator method |
Determination of the mass fraction of haloxyfop-ethyl
HPLC is the main method for determining the mass fraction of haloxyfop-ethyl, and its key steps include:
- Sample preparation:Weigh the sample and dissolve it with the mobile phase.
- Instrument conditions:AD-H Chiralcel-OK column was used, and the detection wavelength was 280 nm.
- Determination steps:After separation by liquid chromatography, the peak area was calculated and the mass fraction was determined using the standard curve.
Background of Standard Formulation and Technological Evolution
High-efficiency haloxyfop-methyl is an important herbicide ingredient. The formulation of its standard reflects the pesticide industry's high attention to product quality and safety. With the modernization of agricultural production, the demand for high-efficiency haloxyfop-methyl is increasing. This standard provides a scientific basis for ensuring product quality.
Implementation Suggestions
In order to better implement the GB/T 34157-2017 standard, it is recommended that:
- Enterprise level: Strengthen the quality control system to ensure that all links meet the standard requirements.
- Testing agencies: Improve testing capabilities to ensure that data is accurate and reliable.
- Regulatory authorities: Increase law enforcement efforts and crack down on unqualified products.
