β¦ Synopsis
A flow spectrophotometric method for the preconcentration and determination of hydrogen peroxide is developed. It is based on the formation of the titanium(IV) peroxo complex and its retention on a minicolumn cation exchanger, elution with sulphuric acid and spectrophotometric detection at 410 nm. The calibration graph is linear over the range 4 x 10e6-6 x 10m5 M. The 2a detection limit is 1 X 10e6 M (34 ng ml-' and the exchange capacity is 1.1 mmol H,O, g-' dry weight.

Reduction of hydrogen peroxide and organic peroxides (t-butyl hydroperoxide and linoleic acid hydroperoxide) was achieved with homovanillic acid as hydrogen donor in the presence of the triethylenetetramine-Fe3+ complex. By the catalytic action of this complex, homovanillic acid is oxidized to its f
