Abstract
A new reagent, 1-(N-methylpyridinium-4-yl-azo)-4-(4-diethylaminophenylazo)naphthalene iodide, can react with sodium 4-dodecylbenzenesulfonate to show a color change in an aqueous phase in the presence of iodide ion. The calibration graph is straight line up to 1.2×10−5 M (1 M=1 mol dm−3); e=3.25×104 1 mol−1 cm−1 at 580 nm.
