| Abstract: | A novel substitutive differential potentiometric stripping analysis(DPSA) for the determination of lead via the bismuth-film electrode with the standard addition method was proposed.In oxalic acid,the sensitive stripping peaks(dt/dE) of the ions were obtained,The method has been applied to determine lead in spirulina platensis samples with satisfactory results. |
