Fertilizers. Determination of trace elements. Determination of mercury by vapour generation (VG) after aqua regia dissolution. | Status: Superseded, Withdrawn

1 Scope This Technical Specification specifies a method for the determination of the content of mercury in fertilizers after extraction with aqua regia and the detection of mercury by vapour generation (VG) coupled to an atomic absorption spectrometer or an inductively coupled plasma-atomic emission spectrometer. A limit of quantification of 0,01 mg/kg is to be expected.
