Carbon nanotube composite coated platinum electrode for detection of Cr(III) in real samples.


This paper demonstrates the application of composite multi-walled carbon nanotube (MWNT) polyvinylchloride (MWNT-PVC) based on 1,5-diphenylcarbazide as chromium ionophore in potentiometric measurement. The sensor shows a good Nernstian slope of 19.52+/-0.40mV/decade in a wide linear range concentration of 6.3x10(-8) to 1.0x10(-2)M for Cr(NO(3))(3). The… (More)
