Lead detection method and reggents utilizing aminolevulinic acid dehydratase and tertiary phosphines |
| abstract |
A method and kit for simplifying and improving the sensitivity and accuracy of a lead assay for a sample solution suspected of containing lead determines the extent of a reaction between a substrate and a disulfide enzyme in the presence of an activating reagent which contains a water-soluble tertiary phosphine reagent so as to increase the activity of the disulfide enzyme for reaction with the substrate. For a colorimetric determination of the enzyme activity a chromophore is formed upon reaction with a selected component of the sample solution in the presence of a colorimetric enhancing reagent. The colorimetric enhancing reagent contains a metal ion such as cupric ion or ferric ion which is soluble in the sample solution. The extent of the chromophore formation is then photometrically determined. |
