摘要

In this research Multi-walled carbon nanotube (MWCNT) surface was modified chemically by acouple of reactions between trimethoxysilyl- propyl-amine (TMSPA) and (2)-hydroxybenzaldehyde(2-HBA) which is then characterized by FT-IR technique. This new material (MWCNT-SPIMP) in2+ carbon paste electrode, matrices selectively the Cu ion. The influence of variables including sodiumtetraphenylborate ((C6H5)4BNa), some amount of MWCNT-TMSPA, Nujol and graphite powder onelectrode response has been investigated and their value was set as graphite powder: NaTPB: Nujol:carrier in the mass (mg) ratio of 150/6.0/30.0/50 for this electrode. At the optimum it was set as the-8 proposed ion selective electrode response, and is linear over the wide range concentration of 1.0 10-2 -1 to 1.0 10 mol L with slopes of 30.01 per decade of ion concentration and detection limit of 8.8 -9 -1 10 mol L . The response of this electrode is independent of pH in the range of 3.0-6.0 with a shortresponse time of about 5s. This electrode successfully has been applied for potentiometric2+ determination of Cu ion content in various real samples and as indicator electrodes for potentiometrictitration.
