Abstract
Synthesis and characteristics of a new chromogenic reagent, 4-(2'-thia zolylazo)-6-formyl-resorcinol (TAFR) has been reported. The optimum co nditions for spectrophotometric determination of lead (II) using TAFR is present. At pH 7.5-8.0, TAFR forms a 1:1 red complex with lead (II) with molar absorptivity 1.62 x 10(4) l mol(-1) cm(-1) at 565 nm. Beer 's law is obeyed in the range of 0-8 mu g/25 mi Pb (II). The method ha s been applied for the direct determination of lead (II) in water samp les.
