GB/T 39356-2020 Determination of total nickel,total cobalt,total selenium, total vanadium, total stibium,total thallium in fertilizers — Inductively coupled plasma optical emission spectroscopy

Scope: This standard specifies the method for the determination of total nickel, total pot, total selenium, total vanadium, total lock, and total ingot content in fertilizers by inductively coupled plasma optical emission spectrometry (ICP-OES). This standard applies to the determination of total zhao, total sulfur, total selenium, total vanadium, total lock and total chromium in fertilizers. The detection limit of this standard method is as follows: Ni (Ni) is 0.02 mg/Kkg; Co (Co) is 0.02 mg/Kg; Selenium (Se) is 0.4 mg/kg; Vanadium (V) is 0.02 mg/kg; (Sb) is 0.1 mg/kg; feed (TI): 0.01 mg/kg when using 6.2.2 a) and 0.02 mg/kg when using 6.2.2 b).
