Scope
GB/T 41707-2022 is the English-translated version of 常温铜系脱砷剂.
GB/T 41707-2022 is the Chinese national product standard for copper-based adsorbents that strip arsenic at room temperature. It specifies the technical requirements, test methods, inspection rules, marking, packaging, transport and storage, and the documents that travel with the product.
It applies to adsorbents whose main active component is copper oxide, made by the precipitation method or the mixed milling method, and used to remove arsine from light hydrocarbons.
The product is a black or grey-black solid in spheres, strips or columns, and its technical indicators are set out in a table. It also cautions that users should have practical experience of laboratory work and remain responsible for their own safety measures.
It cites GB/T 191, GB/T 6678, GB/T 8170, GB/T 31192, GB/T 31536 and HG/T 2782, was issued on 14 October 2022 and has applied since 1 May 2023.
