英文名称：Soil, treated biowaste, sludge and waste — Digestion of aqua regia soluble fractions of elements

发布日期：2020-08

标准范围

This document specifies two methods for digestion of soil, treated biowaste, sludge and waste by the
use of an aqua regia digestion.
Digestion with aqua regia will not necessarily accomplish total decomposition of the sample. The
extracted analyte concentrations may not necessarily reflect the total content in the sample but
represent the aqua regia soluble metals under the condition of this test procedure. It is generally agreed that for environmental analysis purposes, the results are fit for the intended purpose to protect the environment.
This document is applicable for the following elements:
Aluminium (Al), antimony (Sb), arsenic (As), barium (Ba), beryllium (Be), boron (B), cadmium (Cd),
calcium (Ca), chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), lead (Pb), magnesium (Mg),
manganese (Mn), mercury (Hg), molybdenum (Mo), nickel (Ni), phosphorus (P), potassium (K),
selenium (Se), silver (Ag), sodium (Na), strontium (Sr), sulfur (S), tellurium (Te), thallium (Tl), tin (Sn),
titanium (Ti), vanadium (V), and zinc (Zn).
This document can also be applied for the digestion of other elements, provided the user has verified
the applicability.
