适用范围:This standard specifies a method of determining zinc concentrations ranging from 0,01 mg/I to 2 mg/I innatural 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 determinedin each laboratory by calibration experiments.Depending on the objective, if water contains undissolved zinc, the determination may be limited to thedissolved component by filtering the sample prior to stabilization or the sample may be subjected to suitabledigestion.The content of total zinc in sludges and sediments can be determined after digestion by the method specifiedin DIN EN 13346.
