a highly sensitive reagent for direct spectrophotometric dertermination of ultramicro quantities of metals
has been syhthesized. The complex reaction of TPP with Mn(II) has been studied. A sensitive method for the determination of trace Mn(II) with TPP has bocn established. The apparent molar absorptivity of the Mn(II) complex is 1.14x105L. mol.-1cm-1at 466nm. The method has been applied to the determination of trace Mn in human hair with satisfactory results
