CdO nanoparticles: robust inorganic additive for cadmium selective polymeric electrode based on N-phenylaza-15-crown-5
This study presents the development of a new and sensitive polyvinyl chloride electrode based on cadmium oxide (CdO) nanoparticles and N-phenylaza-15-crown-5 for the selective determination of cadmium cations. To this end, synthesized cadmium oxide nanoparticles were characterized through XRD, FT-IR and FESEM analysis. Then, CdO nanoparticles were applied as a modifier for the fabrication of the proposed electrode. The optimum membrane composition to construct the electrode comprised poly(vinyl chloride) (30%), nitrobenzene (61%), cadmium oxide nanoparticle (3%) and N-phenylaza-15-crown-5 (6%). The Nernstian slope of the electrode was obtained 27.3 ± 0.3 mV/decade in the 1.0 × 10–8 to 1.0 × 10–1 M concentration range, and the detection limit was obtained as 9.8 × 10–9 M. The response time of the electrode was short (5 s), while its reversibility and lifetime were high. It was revealed that the operation pH range of the electrode ranged between 2 and 9, and the electrode had a very good selectivity to cadmium cations among the other interfering ions. Further, the electrode was successfully used as a potentiometric sensor in complexometric titrations and the measurement of cadmium cations in the environmental waters.
期刊介绍：
The Journal of Inclusion Phenomena and Macrocyclic Chemistry is the premier interdisciplinary publication reporting on original research into all aspects of host-guest systems. Examples of specific areas of interest are: the preparation and characterization of new hosts and new host-guest systems, especially those involving macrocyclic ligands; crystallographic, spectroscopic, thermodynamic and theoretical studies; applications in chromatography and inclusion polymerization; enzyme modelling; molecular recognition and catalysis by inclusion compounds; intercalates in biological and non-biological systems, cyclodextrin complexes and their applications in the agriculture, flavoring, food and pharmaceutical industries; synthesis, characterization and applications of zeolites.
The journal publishes primarily reports of original research and preliminary communications, provided the latter represent a significant advance in the understanding of inclusion science. Critical reviews dealing with recent advances in the field are a periodic feature of the journal.
