Kinetic spectrophotometric determination of trace amounts of nitrite ion using potassium bromate-murexide mixture in acidic media
A new, simple, rapid, and cheap method for determination of trace amounts of nitrite ion is reported.Determination is based on reduction of bromate ion by nitrite ion, in the presence of murexide inacidic media. During reaction of bromate ion with nitrite ion, the reaction mixture is decolorized.The absorbance changes is then monitored spectrophotometricaly at 520 nm, at 25 °C. Dynamicrange of ...

متن کاملcatalytic spectrophotometric determination of vanadium (iv) based on the oxidation of alkali blue by potassium bromate
a simple, rapid and sensitive spectrophotometric method has been proposed for the determinationof vanadium (iv). the method is based on the catalytic effect of v (iv) on the oxidation of alkali blue bypotassium bromate at ph 4. the rate of decrease in the absorbance of alkali blue (at 572 nm) wasproportional to the concentration of v (iv) in the range of 100-6000 ng ml-1. the detection limit wa...
متن کاملSensitive Kinetic Spectrophotometric method for Trace determination of Cerium (IV) Based on decolarization of Nile blue by potassium Periodate
A simple and sensitive kinetic spectrophotometric method for the determination of trace amounts of cerium (IV), based on the catalytic effect of Ce (IV) on the oxidation of Nile blue (NB) by potassium periodate is described. The reaction rate was monitored spectrophotometrically by measuring the decrease in absorbance of NB at 636 nm. The detection limit of the method was 0.15 g ml and the line...
