| Abstract: |
| A novel disposable electrochemical sensor was fabricated by sputtering gold film and modifying multi walled carbon nanotubes(MWCNTS) on a low cost polyethylene terephthalate(PET) plastic as electrode substrate.The surface morphology of the working electrode was observed by scanning electron microscopy(SEM).The performance of the working electrode in different stages was characterized by cyclic voltammetry(CV).Under the optimal conditions,the nonylphenol(NP) was investigated by linear sweep voltammetry(LSV).Results showed that there was an excellent linear relationship between peak current of the proposed electrode and nonylphenol in the concentration range of 005-5 mg/L,with a detection limit of 003 mg/L.The spiked recoveries ranged from 920% to 103% with relative standard deviations(RSDs) less than 16%.The proposed electrode is low cost,easy to fabricate and available for small lot production.Furthermore,it could prevent itself from the cross contamination of electrode surface in different samples.It was applied to the detection of nonylphenol migration from real plastic samples with satisfactory results. |
