DS CEN/TS 16319:2012

Plehra kimike - Përcaktimi i gjurmëve të elementëve - Përcaktimi i kadmiumit ,kromit,hekurit dhe nikelit nga spektrometria e emetimit atomik të plazmës të çiftezuar induktivisht (ICP-AES) pas tretjes së ujit mbretëror

Fertilizers - Determination of trace elements - Determination of cadmium, chromium, lead and nickel 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 cadmium, chromium, nickel and lead in fertilizers with inductively coupled plasma atomic emission spectrometry (ICP-AES) after extraction with aqua regia. Limits of quantification are dependent on the sample matrix as well as on the instrument, but can roughly be expected to be 0,3 mg/kg for Cd and 1 mg/kg for Cr, Ni and Pb.
