A simple, sensitive, and selective method for rapid determination of nitrite is described which is based on its catalytic effect in the reaction between thymol blue and bromate in acidic media. The reaction is monitored spectrophotometrically by measuring the decrease in absorbance at 543 nm by a fi

A sensitive kinetic fluorimetric flow injection method has been developed for the determination of Ag(I) over the range 100-2500 ng. The method is based on the catalytic effect of Ag(I) on the reduction reaction of safranine by iodide. Method development includes optimization of reagent concentratio
