Abstract
A procedure has been developed for the photometric determination of he terocyclic azo compounds 1-(2-pyridylazo)-2-naphthol (PAN), 4-(2-pyrid ylazo)resorcinol (PAR), 1-(2-thiazolylazo)-2-naphthol (TAN), and 4-(2- thiazolylazo)resorcinol (TAR) by the reaction of oxidation by cerium(I V) salts. This procedure is applied to determining 5-100 mu mol/g of h eterocyclic azo compounds immobilized on S-80 silica gel and employed in test methods as test reagents.
