Manganese ferrite nanoparticles were produced by applying the combustion technique using the manganese acetate and ferric nitrate as the starting material. Analytical techniques like FESEM and TEM were utilized to characterize the synthesized materials. The typical size was observed in the range of 12 to 14 nm with a cubic structure. The synthesized material was used as an electrochemical senso...

Rapid and facile preparation of the cheap modified electrode materials is an important parameter in development of the efficient electrochemical sensor for industrial scale production and mass-market usage. In the present work, the carbon paste electrode modified with multi-walled carbon nanotubes (MWCNTs) was prepared for sensitive determination of lead (Pb) ion in the presence of bismuth (Bi)...

a carbon paste electrode modified with cobalt (ii) phthalocyanine (copc) was used as a sensitive potentiometric sensor for determination of ascorbic acid in aqueous solutions. the potential response of the electrode is a linear function of ascorbic acid concentration over the range 5 10 to 10 m (?1- 1800 µg ml ) with a nernstian slope of 56 mv at ph 7. the limit of detection was 0.2 µg ml ascor...

In this study, a specific CH4 sensor is fabricated based on interdigitated electrode that modified with core-shell of tungsten carbide/tin oxide (WC/SnO2) nanoparticles by wet chemical method in different percents of carbon and tungsten. The morphology of wet chemical-synthesized WC/SnO2 core-shell was evaluated by different methods such as patterned X-ray d...

In the present work, a new sensor for morphine (MO) measurement, based on modification of screen-printed carbon electrode (SPE) by using magnetic core shell manganese ferrite nanoparticles was reported. The electrochemical behaviour of MO was investigated in phosphate buffer solution (pH 7.0) by voltammetry. The electrochemical response of the modified electrode toward morphine was studied by m...

This paper presents an optimal integrated instrumentation sensor network design methodology for complex nonlinear chemical process plants using a Combinatorial Particle Swarm Optimiazation (CPSO) engine. No comprehensive sensor network design approach has been addressed yet in the literature to simultaneously incorporate cost, precision and reliability requirements for nonlinear plant...
