Abstract: | The determination of nickel in atmospheric aerosols, collected on filter paper, is performed by thermal neutron activation
analysis using the65Ni (T=2.56 h) isotope. Liquid-liquid extraction and anion-exchange are applied in the chemical separation. The absolute sensitivity
of the method is ≌0.02 μg Ni. The relative sensitivity is 0.005 μg Ni/m3 if an air sample of about 1000 m3 is used. |
