This European Standard specifies methods of digestion with aqua regia. Solutions produced byThe methods aresuitable for analysis e.g. by atomic absorption spectrometry (FLAAS, HGAAS, CVAAS, GFAAS), inductivelycoupled plasma emission spectrometry (ICP-OES) and inductive coupled plasma mass spectrometry (ICP-MS).The digestion with aqua regia will not necessarily release all elements completely. However for mostenvironmental application and waste characterizationThe results fit forThe purpose.The methodCa, Cd, Cr,is applicable toThe digestion of waste for example forThe following elements:AI, Sb, As, B, Ba, Be,Co, Cu, Fe, Pb, Mg, Mn, Hg, Mo, Ni, P, K, Se, Ag, S, Na, Sr, Sn, Te, Ti, TI, V, Zn
