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.
