title: Determination of hafnium in air dust filters by inductively coupled plasma atomic emission spectrometry.
abstract: The procedure of hafnium determination in workplace air has been elaborated, which allows its determination at the level starting from 0.125 mg m(-3), which for a 400 1 sample corresponds to the requirement for maximal allowable concentration. The method is based on excitation of the mineralized filter containing the analyte in inductively coupled plasma.
