Abstract EN

A new mode in the Semi-automated on-line analysis for lead (II) via chemiluminescence system of Lucigenin-H2O2-OH--Lead (II) which gives a blue-green chemiluminescence, when Lucigenine is oxidized by hydrogen peroxide in alkaline medium was studied.

Measurement of the generated light in a flat-spiral glassy cell designed for this purpose were achieved using advanced electronic detection system (with a multiple choice of readout systems).

A relation for the variation of response with concentration expand from 1-15 µg.ml-1 with % linearity of 97.6 % while a % of linearity 99.44 % using a quadratic equation.

The quadratic equation represent the data much more preferably in which a picogram level of detection limit was achieved.

Also the study was carried out for interferring effect.
