This document specifies a method for the determination of the following elements in digestates of aqua regia, nitric acid or mixture of hydrochloric (HCl), nitric (HNO3) and tetrafluoroboric (HBF4)/hydrofluoric (HF) acids of soils , treated biowaste, waste, sludge and sediment: Aluminum (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). This method is also applicable to other extracts or digestates from, for example, DTPA extraction, fusion methods or total digestion methods, provided the user has verified the applicability. This method has been validated for the elements indicated in Table A.1 (sludge), Table A.2 (compost) and Table A.3 (soils). It is applicable to other solid matrices and other items listed above, provided the user has verified applicability. This method is also applicable to the determination of major, minor and trace elements in digestates of aqua regia and nitric acid as well as in eluates of construction products (EN 17200[22]). NOTE Construction products include, for example, mineral products; bituminous products; metals; wood products; plastics and rubbers; sealants and adhesives; paints and coatings.
