摘要：

The effect of non-ionic surfactant (Triton X-100) on the sensitive, simple and inexpensive spectrophotometric method was developed for the determination of lead(II) with potassium benzyl xanthate (KBX). Lead was complexed with potassium benzyl xanthate in presence of non-ionic surfactant (Triton X-100). Absorption spectrum of Pb(KBX)(2) complex in the presence of non-ionic surfactant medium shows a peak at 370 nm. The molar absorptivity of the complex was 6.723 x 10(4) dm(3) mol(-1) cm(-1) and Sandell's sensitivity was 3.2478 x 10(-3) mg cm(-2). The system obeys Beer's law in the concentration range of 0.25 to 10.0 ppm. The composition of the complex (metal:ligand) was 1:2. The method was employed for the determination of lead in industrial effluents and ground water samples.
