Abstract
The molar absorptivities of the lanthanide complexes with chlorophosphonazo III over the pH range 1-4 were found to increase with atomic number to maximum values near 7000 1.mole(-1).mm(-1) for holmium, erbium and thulium and then to decrease slightly for ytterbium and lutetium. The complexes were found to be stable for up to 65 hr. The addition of alkali metal salts depressed the apparent absorptivity of the complexes but no interference was observed for the phosphate ion.
