Fertilizers and liming materials - Determination of arsenic by inductively coupled plasma-atomic emission spectrometry (ICP-AES) after aqua regia dissolution
This European Standard specifies a method for the determination of the content of arsenic in fertilizers and liming materials using inductively coupled plasma-atomic emission spectrometry (ICP-AES) after aqua regia dissolution. Limits of quantification are dependent on the sample matrix as well as on the instrument, but can roughly be expected to be 1,5 mg/kg for As.
NOTE The term fertilizer is used throughout the body of this European Standard and includes liming materials unless otherwise indicated.

Ta evropski standard določa metodo za določevanje vsebnosti arzena v gnojilih in sredstvih za apnjenje z atomsko emisijsko spektrometrijo z induktivno sklopljeno plazmo (ICP/AES) po raztapljanju v zlatotopki. Meje kvantifikacije so odvisne od matrice vzorca in instrumenta, vendar so za As običajno približno 1,5 mg/kg.
OPOMBA: Izraz »gnojilo« se uporablja v celotnem glavnem delu tega evropskega standarda in vključuje sredstva za apnjenje, če ni navedeno drugače.

approximately 1,42 g/ml. 6.4 Mixed acid solution of 0,8 mol/l nitric acid and 1,8 mol/l hydrochloric acid. Mix 150 ml of hydrochloric acid (6.2) and 50 ml nitric acid (6.3) to 1,0 l of water (6.1). 6.5 Standard stock solution arsenic standard stock solution, e.g.
= 1 000 mg/l in arsenic. Use suitable stock solutions. Single-element stock solutions with adequate specification stating the acid used and the preparation technique are commercially available. It is recommended to use a commercially available standard stock solution for arsenic. 6.6 Working standard solutions. Depending on the scope, different working standard solutions may be necessary. 6.6.1 Working standard solution I,
= 100 mg/l for arsenic. Dilute 10,0 ml of the stock solution of arsenic (6.5) to 100,0 ml with the mixed acid solution (6.4) in the same 100 ml flask. This solution is used to prepare spiked test solutions and standard and calibration solutions. 6.6.2 Working standard solution II,
= 10 mg/l for arsenic. Dilute 10,0 ml of the working standard solution I (6.6.1) to 100,0 ml with the mixed acid solution (6.4) in a 100 ml flask. This solution is used to prepare spiked test solutions and calibration solutions. 7 Apparatus 7.1 Common laboratory glassware. 7.2 Analytical balance, capable of weighing to an accuracy of 1 mg. 7.3 Inductively coupled plasma-atomic emission spectrometer, with axial or radial viewing of the plasma and with suitable background correction. The settings of the working conditions (e.g. gas flows, RF or plasma power, sample uptake rate, integration time, number of replicates) shall be optimized according to the manufacturer’s instructions. Radial viewing of the plasma may be used if it can be shown that the limit of quantification for arsenic is below the required legal limit values. The use of axial orientation of the viewing optics requires good control of the matrix effects coming from “easily ionisable elements” (i.e. the influence of easily ionisable elements in varying concentrations on the signal intensities of the analytes). For alkali-elements, this can be achieved by adding caesium-chloride solution (CsCl). In general, matrix matching of calibration solutions or calibration by standard SIST EN 16317:2013+A1:2017
