79 Perpetration of electrochemical sensor for determination of some pharmaceutical compound based on ferrite nickel magnetic nanoparticles decorated multiwall carbon nanotubes with differential pulse voltammetry Behjat Saeid Emil farzaneh saeid@ymail com Department of Chemistry Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiAli A Ensafi Email Ensafi@cc iut ac irAbstract It is very necessary to develop a sensitive and selective method for the determination oftrace catecholamine due to its physiological function and the diagnosis of some disease inclinical medicine In this research the application of nanomaterials is proposed such as multiwallcarbon nanotubes MWCNTs and ferrite nickle nanoparticles NiFe2O4 for the modification ofglassy carbon electrode to measure epinephrine and methyldopa The electrochemical behaviorof the modified electrode with the nanomaterials in an aqueous buffer solution is studied for thedetermination of epinephrine EP and methyldopa MD using differential pulse voltammetry DPV and electrochemical impedance spectroscopy EIS The results showed that the chemically modified electrode exhibits efficient synergicactivity in the oxidation of EP and MD The different parameters on the response of the electrodeto measure EP and MD were studied Under the optimized conditions and by DPV two linearsegments were obtained the first segment was from 0 9 to 40 0 M and the second part wasfrom 40 0 to 800 0 M EP with a detection limit of 0 09 M The relative standard deviation for6 repeated measurements for 50 0 M EP was obtained 0 9 The interference of foreignsubstances on the EP was investigated too The calibration curve for MD was linear in theconcentration range of 0 5 to 900 0 M MD with a limit of detection of 0 08 M MD Therelative standard deviation for 50 0 M MD was 1 2 The interference of foreign substances inthe determination of MD was investigated too Finally the proposed sensor was successfully usedfor the determination of MD and EP in real sample such as human urine tablet and plasma Key wordsCatecholamine Epinephrine Methyldopa Multiwall carbon nanotubes Ferrite nickelnanoparticle Differential pulse voltammetry
