چکیده:

A comparatie study was made between three types of Pb+2 ion-selective electrodes: PVC membrane electrode , copper coated electrode and modified carbon paste electrode based on bis (2-hydroxy-1-naphtyl )-4,4- diaminodiphenyl sulfone BHNDS as a neutral carrier . In this study electrodes with a solid contact give lower detection limitand wider linear range relatie to traditional liquid inner contact and modified carbon paste electrodes.
