Thiazolylazo Dyes as Reagents for Detection and Ring Colorimetric Determination of Copper
Five thiazolylazo dyes namely 5-(2-thiazolylazo)-2,4-dihydroxybenzoic acid, 2-(2-thiazolylazo)-p-cresol, 1-(2-thiazolylazo)-2-naphthol, 4-(2-thiazolylazo)phloroglucinol and 4-(2-thiazolylazo)resorcinol have been found to be suitable reagents for the detection colorimetric determination of copper by ring oven technique. 1-(2-Thiazolylazo)-2-naphthol (TAN) has been found to be the most sensitive reagent.
