description

Automatic flow injection methods for the determination of hydrogen peroxide, dichromate, formaldehyde and bicarbonate in dairy products are proposed. They are based on reaction with vanadium pentoxide, diphenyl-carbazide, fuchsine-sulphur dioxide and alizarin, respectively. Sample pre-treatment (paper and membrane filtration, dialysis) is widely discussed for on-line incorporation. The usefulness of these methods was tested by applying them to different commercial samples, satisfactory results being obtained in all instances.
