Electro‐oxidation and Determination of TRIPELENNAMINE HYDROCHLORIDE (cas 154-69-8) at MWCNT‐CTAB Modified Glassy Carbon Electrode

Add time:09/28/2019    Source:infona.pl

An electrochemical method for the determination of TRIPELENNAMINE HYDROCHLORIDE (cas 154-69-8) (TPA) using cetyltrimethylammoniumbromide‐multiwalled carbon nanotubes modified glassy carbon electrode (MWCNT‐CTAB/GCE) was developed. Because of good electrical conductivity of MWCNT and catalytic behavior of CTAB, new electrode significantly enhances the sensitivity for the detection of TPA. Parameters such as amount of modifier suspension, scan rate, pH of measure solution, heterogeneous rate constant were investigated. The electrode exhibits a linear potential response in the range of 1.0×10−8 M to 3.0×10−6 M with a detection limit of 2.38× 10−9 M. The modified electrode was successfully applied to the determination of TPA in pharmaceutical and real samples.
