Synergistic Chromogenic Reaction of Niobium with Bromopyrogallol Red and Butyl Rhodamine B and Its Application
-
ABSTRACT
Synergistic chromogenic reaction of niobium with bromopyrogallol red and butyl rhodamine B in the presence of hexadecylpyridinium bromide was studied. In the optimized conditions, a multicomponent ionassociated complex was formed. The maximum absorption w
