| Popis: | 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 × 10−6−6 × 10−5 M. The 2σ detection limit is 1 × 10−6 M (34 ng ml−1 and the exchange capacity is 1.1 mmol H2O2 g−1 dry weight. |
