Novel all-solid-state copper(II) microelectrode based on a dithiomacrocycle as a neutral carrier
چکیده انگلیسی

A novel dithiomacrocycle (4-phenyl-11-decanoyl-1,7-dithia-11-azacyclotetradecane-4-sulfide) has been synthesized and used as a new ionophore in order to develop a plasticized poly(vinyl chloride) membrane for copper ion detection. The performance of these novel planar copper(II)-selective potentiometric microelectrodes was investigated using potentiometric measurements. The developed microelectrodes exhibits a good linear response of 29.5 ± 1 mV per decade within the concentration range of 1.0 × 10−6 to 1.0 × 10−2 M (r = 0.9995) of Cu2+. The detection limit was determined as 5.62 × 10−7 M and the selectivity coefficients for possible interfering cations were evaluated. The microelectrodes are suitable for use with aqueous solutions of pH 3.5–6.0 and were found to be insensitive to the nature of the anions used in the sample.
