A simple procedure was developed for the spectrophotometric determination of carbaryl and its hydrolysis product I-naphthol in water. These compounds are extracted into xylene and back-extracted, as the 1-naphtholate, with 0.2 M NaOH. A 600-~1 volume of the alkaline extract is injected into a flow a
A flow-injection spectrophotometric method for the determination of adrenaline and isoprenaline, based on the reaction with metaperiodate, is described. The calibration graphs are linear up to 2X 10e4 M. Flow injection allows the measurement of 120 samples per hour. The method was successfully appli
A flow-injection spectrophotometric method for the determination of hydrazine is described. The method is based on the inhibitory effect of hydrazine on the reaction of thionine with nitrite in acidic media. The decolorization of thionine by the reaction with nitrite was used to monitor the reaction
Mdk samples were analysed spcctrophotometncally for their lactose content usmg flow-lwectlon analysis The methodology IS based on the carmme colour that develops (Amu = 540 nm) when lactose reacts with alkahne methylamme (pH 12 7) Lactose concentrations as low as 0 6 mg ml-' can be readily detected
