摘要：
Isonitrosopropiophenone (HINPP) is proposed as a new reagent for extraction and spectrophotometric determination of Co(II). The reagent reacts with Co(II) to give a yellow coloured complex which can be quantitatively extracted into chloroform at pH 8.0. Molar absorptivity at 355 nm is 2.9466x10(3)1. mol(-1) cm(-1). Beer's law is obeyed in the range 0.5-7 ppm. The proposed method has been used for analysis of Co(II) in real samples.
