Scope

This document specifies a method for the determination of the following elements in aqua regia, nitric acid or mixture of hydrochloric (HCl), nitric (HNO3) and tetrafluoroboric (HBF4)/hydrofluoric (HF) acid digests of soil, treated biowaste, waste, sludge and sediment:
Aluminium (Al), antimony (Sb), arsenic (As), barium (Ba), beryllium (Be), bismuth (Bi), boron (B), cadmium (Cd), calcium (Ca), cerium (Ce), chromium (Cr), cobalt (Co), copper (Cu), dysprosium (Dy), erbium (Er), europium (Eu), gallium (Ga), gadolinium (Gd), germanium (Ge), gold (Au), hafnium (Hf), holmium (Ho), indium (In), iridium (Ir), iron (Fe), lanthanum (La), lead (Pb), lithium (Li), lutetium (Lu) magnesium (Mg), manganese (Mn), mercury (Hg), molybdenum (Mo), neodymium (Nd), nickel (Ni), palladium (Pd), phosphorus (P), platinum (Pt), potassium (K), praseodymium (Pr), rhodium (Rh), ruthenium (Ru), samarium (Sm), scandium (Sc), selenium (Se), silicon (Si), silver (Ag), sodium (Na), strontium (Sr), sulfur (S), tantalum (Ta), tellurium (Te), terbium (Tb), thallium (Tl), thulium (Tm), thorium (Th), tin (Sn), titanium (Ti), tungsten (W), vanadium (V), yttrium (Y), ytterbium (Yb), zinc (Zn) and zirconium (Zr).
The method is also applicable to other extracts or digests originating from, for example, DTPA extraction, fusion methods or total digestion methods, provided the user has verified the applicability.
The method has been validated for the elements given in Table A.1 (sludge), Table A.2 (compost) and Table A.3 (soil). The method is applicable for other solid matrices and other elements as listed above, provided the user has verified the applicability.
This method is also applicable for the determination of major, minor and trace elements in aqua regia and nitric acid digests and in eluates of construction products (EN 17200[22]).
NOTE            Construction products include e.g. mineral-based products; bituminous products; metals; wood-based products; plastics and rubbers; sealants and adhesives; paints and coatings.
