The developed methods were successfully applied to determine copper and lead in some double-base propellants. Beer′s law was obeyed up to 0.42ppm of copper and 1.96ppm of lead at 562nm. with molar absorptivities of 9.3×104 and 6.2×104M-1 cm-1, respectively. The sensitized 1:2 copper- and lead-phenylfluorone chelates were formed within the pH ranges 8.8-9.8 and 8.8-9.5. Maximum sensitization of the color reactions was obtained in the presence of benzyldimethyltetradecylammonium chloride (Zephiramine). The complexation reactions of copper(II) and lead(II) with phenylfluorone in aqueous micellar solutions of different surfactants were investigated.
