Abstract

A new indicator reaction is developed on the basis of manganese catalyzed oxidation of coomassie brilliant blue G250 by potassium periodate with nitrilotriaetic acid as an activator. The detection limit for manganese is 6.76 x 10(-8) g/L. The linear range of determination is 0.02-0.30 microgram/25 mL.
