| Abstract: | The synthesis, characteristics and analytical reactions of di-2-pyridyl ketone thiosemicarbazone are described. This compound reacts with iron(II) (λmax=410mm, ε = 9.3 · 103 1 mol?1 cm?1), nickel(II) (λmax =395 mm ε =19.6·103 10 mol ?1 cm -1), cobalt(II) (λmax = 415 nm. ε = 1.0 · 104 mol?1 cm?1 ) and copper(I) (λmax =395mm ε = 11.3 · 103 mol?1 cm?1) A critical comparison of di-2-pyridyl ketone, picolinaldehyde and bipyridylglyoxal thiosemicarbazones as analytical reagents is given. |
