چکیده مقاله:

An analytical method using natural Analcime Zeolite modified with Neothorin for preconcentration of
lead, in a column system, and their sequential determination by flame atomic absorption spectrometry
(FAAS), was developed. In this work, lead was adsorbed onto natural Analcime Zeolite modified with
Neothorin and then was recovered by 5.0 mL of 2 M nitric acid. Solution of lead passed through a glass
column packed with 100mg of the sorbent material, at pH 5.0, and lead eluted with 2 M HNO3 at a flow rate
of 2.0 mL min-1. A 4.11ppb detection limit for the preconcentration of aqueous solution of lead was obtained.
The relative standard deviation (RSD) for eight replicate determination at the 5g mL-1 lead level was
4.8%.The calibration graph using the preconcentration system was linear from 0.1 to30 g mL-1 in final
solution with a correlation coefficient of 0.9994.This method was successfully applied for determination of
lead in various samples.
