چکیده
|
An electroanalytical sensor amplified with nio-swcnts nanocomposite and 1-hexyl-3-methylimidazolium chloride (hmc) was fabricated and used for determination of phenylhydrazine as a water contaminant. the nio/swcnts nanocomposite was synthesized by a simple and one-pot method (chemical precipitation in this case) and characterized by fesem and eds methods. in continuous, nio-swcnts/hmc/cpe was used as working electrode for investigation electrochemical behavior of phenylhydrazine. in compare to unmodified electrode, oxidation signal of phenylhydrazine was improved about 6.8 times and results confirm a linear dynamic range between 3.0 nm – 350 μm with detection limit 0.8 nm using differential pulse votammetric method (dpv). the ability of nioswcnts/ hmc/cpe as an analytical tool was check for determination of phenylhydrazine in water samples and results confirm powerful ability of suggested sensor for this goal with recovery data 97.8% - 104.35%.
