Ka'idodin Kare Muhalli na Jamhuriyar Jama'ar Sin "HJ637-2018" Ingancin Ruwa Ma'aunin Infrared Spectroscopy na Man fetur da dabbobi da tsire-tsire

Ka'idodin fasaha

Dangane da HJ637-2018 ka'idodin, bayan da aka cire da tetrachloride a karkashin yanayin pH≤2 na samfurin ruwa, an auna man fetur; Bayan an yi amfani da magnesium silicate don kawar da kayan polar kamar man dabbobi da tsire-tsire, an auna nau'ikan man fetur. Abubuwan da ke ciki na man fetur da nau'ikan man fetur suna da lambar raƙuman ruwa na 2930cm-1 (rawar jiki na C-H a cikin rukunin CH2),

Absorption A2930, A2960 da A3030 a 2960cm-1 (girgizar girgizar C-H a cikin rukunin CH3) da 3030cm-1 (girgizar girgizar C-H a cikin zoben ƙanshi), daidai da daidaitawa; Abubuwan da ke cikin man dabbobi da tsire-tsire suna da bambanci tsakanin man fetur da man fetur.
