Electrochemical determination of hydroxylamine through MOWS₂ nano-composite modified electrode

ABSTRACT

Hydro-thermal synthesised MOWS₂ nano-composite has been specified and employed to the modify a screen-printed electrode (SPE) in electro-catalytic voltammetric detection of hydroxylamine. Sensor of MOWS₂ nano-composite has been followed by acceptable function to detect hydroxylamine with a linear range within 0.7–400.0 µM, and a limit of detection (LOD) of 0.2 µM. Results indicated that MOWS₂ nano-composite enjoy high potentials to be used in electrochemical sensing. Moreover, this modified electrode has the benefits of a significant linear association, higher sensitivity and small determination limit, acceptable anti-interference capability and very high stability, resulting in widespread uses in detecting real samples.
