DIN 38405-35-2004 德国对水、废水和淤泥的标准检验法.阴离子(D组).第35部分:用石墨炉原子吸收光谱法测定砷的含量(GF-AAS)(D35)
German standard methods for the examination of water, waste water and sludge - Anions (group D) - Part 35: Determination of arsenic - Method by graphite furnace atomic absorption spectrometry (GF-AAS) (D 35)
The method specified in this standard serves to determine arsenic in water in concentrations by mass ranging
from 2 μg/I to 100 μg/I if a volume of 20 μI is injected. The limit of determination is often lower and shall be
determined in each laboratory by calibration experiments. The method is also suitable for higher
concentrations if the sample is diluted or a smaller volume of the test solution is taken. Arsenic in sludge and
sediments can be determined using suitable digestion methods (see DIN EN 13346).
