NBN EN 13656:2002

This European Standard specifies methods of microwave assisted digestion with hydrofluoric (HF), nitric (HNO3)and hydrochloric (HCL) acid mixture. Solutions produced by the methods are suitable for analysis e.g.by atomic absorption spectometry (FLAAS,HGAAS,CVAAS,GFAAS), inductively coupled plasma emission spectometry(ICP-OES) and inductive coupled plasma mass spectometry(ICP-MS). The method is applicable to the microwave assisted acid digestion of waste for example for the following elements:Al,Sb,As,B,Ba,Be,Cd,Cr,Cu,Fe,Pb,Mg,Mn,Hg,Mo, Ni,P,K,Se,Ag,S,Na,Sr,Te,Ti,Tl,V,Zn.
