Introduction

Interpretation of GB/T 36791—2018 National Standard of the People's Republic of China

Analysis of the background of standard formulation and technological evolution

Brominated organic flame retardant chemicals are widely used in building materials, textiles and electronic products, and their safety and environmental protection are increasingly concerned. In order to ensure product quality and safety in use, GB/T 36791—2018 standard came into being, stipulating the method of determining bromine content by oxygen bomb combustion-ion selective electrode method.

The formulation of this standard is based on the development of chemical analysis technology, especially the progress of ion selective electrode technology. The accuracy and reliability of the measurement results are ensured by precisely controlling the experimental conditions and optimizing the analysis process.

Standard implementation suggestions

1. Laboratory conditions requirements:

Equipped with oxygen bomb and bromide ion selective electrode in accordance with GB/T14402.
Analysts need to undergo professional training and be familiar with laboratory safety regulations.
Ensure that the purity of reagents and experimental water meet the third-level standard (GB/T6682).

2. Key points of operation:

Strictly control the combustion conditions, including oxygen pressure and combustion time.
Pay attention to the accuracy of sample weighing to avoid introducing errors.
Calibrate the ion selective electrode in time to ensure measurement accuracy.

3. Data processing suggestions:

Establish a complete standard curve database and verify the electrode performance regularly.
Analyze the source of abnormal data to eliminate experimental errors.
Use statistical methods to evaluate the precision and accuracy of the measurement results.
