چکیده
|
The possibility of the use of cobalt(iii) oxyhydroxyde as an electrode modifier for hydrazine detection has been investigated. the mechanism for the electrochemical oxidation of hydrazine over coo(oh) has been suggested,and the correspondent mathematical model was developed and analyzed. the optimal ph for electroanalytical efficiency of the system is between 7 and 12. strongly alkaline media promote the direct hydrazine oxidation and may destroy the modifying material. the oscillatory and monotonic instabilities´ possibility has been also investigated. these instabilities may be caused by surface and electrochemical factors. © 2016 by cee (center of excellence in electrochemistry).
