3 Security
3.1
Acrylonitrile for industrial use is a highly dangerous, highly toxic and volatile, through the skin and the respiratory tract is absorbed by the body, it should be analyzed in the hood
Carried out, and to provide labor protection measures to protect the skin and respiratory organs for personnel exposed to acrylonitrile.
4 General Provisions
Unless otherwise stated, all reagents were of analytical grade, the water used are in line with GB/T 6682 tertiary water specifications.
Used in the analysis standard solution, preparations and products, did not indicate when the other requirements, according to GB/T 602 and GB/T 603 requirements preparation.
5 Sampling
