Abstract:A very simple, highly selective and non - extractive Spectrophotometric method for the trace amounts of lead (II) has been developed. Salicylaldehyde Isonicotinoylhydrazone (SAINH) has been proposed as a new analytical reagent for the direct non- extractive Spectrophotometric determination of lead (II). The reagent reacts with lead in an basic medium (pH 8.25, ammonium hydroxide and ammonium chloride buffer) to form a yellow colored 1: 1(M : L) complex. The reaction is instantaneous and the maximum absorption was obtained at 390 nm and remains stable for 3h. The molar absorptivity and sandell’s sensitivity were found to be

.Linear calibration graphs were obtained for 1.0 -9.0 μg/ml of lead (II). The method is highly selective for lead and successfully used for the determination of lead in various water samples.
