DIN 38406-8:2004 PDF

Scope: 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.
