Abstract:

 

Pb ions can react sensitively with dibromo-p-methylsulfonazo (DMSA) to form a  blue complex, whose absorption is maximal at 630 nm. By means of the  light-absorption ratio variation approach (LARVA), the direct determination  of Pb was developed in 0.3 M nitric acid and plots of D  Ar-1 vs. cPb-1 are linear where D Ar is the light-absorption  ratio variation and cPb Pb(II) concentration is between 0 and 5.0 mg/L.  The limit of detection (3s) of Pb(II) is only 0.02 mg/L. This method  was applied to direct analysis of natural water with satisfactory results.
