DIN 38406-8-2004《德国对水、废水和淤泥的统一检验法 阳离子(Ｅ组) 第8部分：锌的测定 空气乙炔火焰中的原子吸收分光光度法(E8)》

This standard specifies a method of determining zinc concentrations ranging from 0,01 mg/I to 2 mg/I in
natural waters and waste water by atomic absorption spectrometry (AAS) using an air-ethyne flame. Higher concentrations can be determined by dilution. The limit of determination is often lower and can be determined
in each laboratory by calibration experiments.
Depending on the objective, if water contains undissolved zinc, the determination may be limited to the
dissolved component by filtering the sample prior to stabilization or the sample may be subjected to suitable
digestion.
The content of total zinc in sludges and sediments can be determined after digestion by the method specified
in DIN EN 13346.
