Plehra kimike - Përcaktimi i gjurmëve të elementëve - Përcaktimi i arsenikut nga nga spektrometria e emetimit atomik të plazmës të çiftezuar induktivisht (ICP-AES) pas tretjes së ujit mbretëror

Fertilizers - Determination of trace elements - Determination of arsenic by inductively coupled plasma-atomic emission spectrometry (ICP-AES) after aqua regia dissolution

Scope

This Technical Specification specifies a method for the determination of the content of arsenic in fertilizers 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.
