Abstract A method has been developed for the automatic potentiometric titration of sulfate in water-soluble colors, which has the advantage of requiring little sample preparation and attention. A platinum indicating electrode is used with a coated silver reference electrode. The colors are dissolved in 75% alcohol. The sulfate is titrated with lead nitrate solution, using a Hiranuma recording automatic titrator. The method is applicable to the determination of sulfate in all sulfonated certifiable water-soluble colors except External D&C Green No. 1. It is not applicable to the determination of sulfate in the certifiable water-soluble fluorescein colors, namely, FD&C Red No. 3, D&C Orange No. 11, D&C Red No. 22, D&C Red No. 28, and D&C Yellow No. 8. The method is also not applicable to D&C Red No. 19. The

The sensitivities of lead in aqueous and organic media by atomic-absorption spectroscopy using lead lines 2170 Å, 2833 A, and 4058 Å, and an oxy-hydrogen or oxy-acetylene flame were studied. When lead in aqueous solution was complexed as K2PbI6 and the complex extracted into methyl isopropyl ketone, a threefold increase in sensitivity relative to the aqueous solution of lead (as lead nitrate) was obtained. Using a 178-mm-long adapter on the top of a Beckman integral aspirator—burner (oxy-hydrogen), a sensitivity (in ppm/1% absorption) of 0.007 and a standard deviation of 0.014 ppm were obtained with a sample containing 0.1 ppm lead. Results obtained with oxy-hydrogen and oxy-acetylene flames have been discussed, and the precision and detection limits indicated. A procedure to determine lead in ppb—ppm level by extracting lead as K2PbI6 in methyl isopropyl ketone has been prescribed.
