| Abstract: | Lead 8-quinolinolate extracted into chloroform is adsorbed on the electrodes of a piezoelectric quartz crystal. The change in frequency of the crystal is used to measure the lead concentration over the range 3 × 10-6–5 × 10-5 M in aqueous solution. The interferences of Fe(III), Ni, Co(II), Zn, Cd and Ag(I) can be masked byl-ascorbic acid and cyanide. |
