Title
Potentiometric lead(II) ions recognition by liquid membrane electrodes incorporating methoxy substituted arylenevinylene derivatives
Author
Abstract
The potentiometric responses towards lead ions of liquid membrane electrodes containing arylenevinylene derivatives are reported. The membranes respond to lead ions in the activity range 10(-6) - 10(-3) M and show good selectivity against common interfering mono- and doubly-charged cations. The new ligands demonstrate low affinity for protonation. 1 mol % (vs the ionphore) of potassium tetrakis(p-chlorophenyl)borate was used as a lipophilic anionic salt to improve the selectivity. The ligands selected for the present Study allow estimating the influence of olefinic double bounds, the number of aromatic rings and the number and position of methoxy groups on recognition process of the lead ions.
