Abstract:
OBJECTIVEAn atomic fluorescence (AFS) method was developed to determine germanium hydride in the air of workplace.
METHODGermanium hydride in the air of workplace was collected by charcoal tube, and desorbed by nitric acid followed filtration with 0.22 microm cellulose filter, the AFS was used to determine Germanium in the desorbed solution.
RESULTSThe linear was good at the range of 0.85-300 microg/L with the correlation coefficient of 0.9993; the LOD and LOQ were 0.51 microg/L and 0.000 17 mg/m3, respectively. The recovery was ranged from 90% to 106%, the RSD of intra- and inter- precision were 3.3%-5.9% and 3.7%-6.3%.
CONCLUSIONThe linear range, sensitivity and precision of the method were all satisfied for the determination of germanium hydride in the air of workplace.
