1009-1010Synthesis and characteristics of a new chromogenic reagent, 4-(2'-thiazolylazo )-6-formyl-resorcinol (TAFR) has been reported. The optimum conditions 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 104 I mol-1 cm-1 at 565 nm. Beer's law is obeyed in the range of 0-8 µg/25 ml Pb (II). The method has been applied for the direct determination of lead (II) in water samples
