Determination of cadmium: Instrument of atomic absorption spectrophotometer Analytik Jena®
ContrAA30 (Analytik Jena AG, Germany) was operated with flame C2H2 in water. Output pressure
of acetylene was operated on 80-100 kPa, the pressure of air was operated on 300-600 kPa. The
velocity of air to flame was operated at 50 L hG1
for Cd and Pb. Burner type used is burner with
wide 100 mm and high in 6 mm. A-10.0 mL sample solution is poured in flask and then the
absorbance was measured in wave lengths of 228.8 nm for Cd and 217.0 nm for Pb.
