Trace measurement of nickel in orthodontic cages with carbon paste electrode modified multi-walled carbon nanotubes by potentiometric method
Journal Title: Journal of Research in Medical and Dental Science - Year 2017, Vol 5, Issue 3
Abstract
The utility of carbon paste electrode modified with 2-Amino acetophenone isonicotinoyl hydrazone (2- AAINH), for the potentiometric determination of Ni(II) in aqueous medium is demonstrated. The electrode exhibits linear response to Ni(II) over a wide concentration range (7.3×10−8–9.1×10−2) with Nernstian slope of 29±0.5 mV per decade. It has a response time of about 50 s and can be used for a period of two months with good reproducibility. The detection limit of this electrode was 5.0×10−7 M. The proposed electrode shows a very good selectivity for Ni(II) over a wide variety of metal ions. This chemically modified carbon paste electrode was successfully used for the determination of Ni(II) in electronics waste sample solution.
