3. To determine palladium in a solution using the fixed concentration method, the reaction of a-naphthylamine oxidation with nitrate ions catalyzed by Pd(II) compounds was used. Determine the concentration of palladium (μg/ml) in the test solution if the following results were obtained when measuring the time t required to achieve a fixed optical density:
Parameters Standard solutions Test solutions
CPd, μg/ml 1 2.3 2.8 3.5 4.5 - - - -
t, min 18.2 7.7 6.3 5.1 4 12.0 7.1 4.4 5.5
Solution for option 1
