Fertilizers and liming materials - Determination of mercury by vapour generation (VG) after aqua regia dissolution

This European Standard specifies a method for the determination of the content of mercury in fertilizers and liming materials 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.
NOTE   The term fertilizer is used throughout the body of this European Standard and includes liming materials unless otherwise indicated.

Engrais et amendements minéraux basiques - Détermination du mercure par génération de vapeur (VG) après digestion à l'eau régale

Gnojila in sredstva za apnjenje - Določevanje živega srebra s tehniko hladnih par po raztapljanju v zlatotopki (vključno z dopolnilom A1)

Ta evropski standard določa metodo za določevanje vsebnosti živega srebra v gnojilih in sredstvih za apnjenje po ekstrakciji z zlatotopko in določevanje živega srebra s tehniko hladnih par (VG) z atomskim absorpcijskim spektrometrom ali atomskim emisijskim spektrometrom z induktivno sklopljeno plazmo. Pričakovana je meja kvantifikacije 0,01 mg/kg. OPOMBA: Izraz »gnojilo« se uporablja v celotnem glavnem delu tega evropskega standarda in vključuje sredstva za apnjenje, če ni navedeno drugače.
