Flow spectrophotometric method for determination of hydrogen peroxide using a cation exchanger for preconcentration

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. T...

More Information
Summary: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 H 2O 2 g −1 dry weight.
