Abstract

A new KINETIC SPECTROPHOTOMETIC method for the DETERMINATION of trace amount Chromium (III) in Tea real samples has been described based on it s the catalytic effect on the oxidations of 1-(2 -PyridylAzo)-2- Naphthol, (PAN), by potassium bromated in sulfuric acid. The reaction is followed spec- trophotometrically by measuring the decrease in the absorbance at 469 nm. Under the optimum conditions of 0.2 molL-1 sulfuric acid, 1.0×10-4 molL-1, 1- (2 -PyridylAzo)-2- Naphthol, (PAN), 0.01 molL-1 potassium bromate at 35oC, calibration graph in the rang of 0.001-0.06 ngL-1 Chromium (III). Concentration was obtained with detection limit of 0.2303 g mL-1 by the fixed-time method of 5.5 min. The relative standard deviation for 0.05AngL-1 Chromium (III) is %90. No serious interference was identified. The applicability of the method was demonstrated by the DETERMINATION of the Chromium (III) in Water, Vegetables and blood samples.
