摘要

The applicability of Curcumin (CRC) as a medicinal remedy for various health issues and as an antiinflammatoryagent, it is of great importance to develop an effortless, sensitive methodology for itsdetermination. In the present research, CRC was determined electrochemically via voltammetrictechniques using poly(L-arginine) modified carbon nanotube paste sensor (PArMCNTPS). Differentparameters (pH, scan rate, number of polymerisation cycle) were optimised using cyclic voltammetry.CRC displayed well-defined oxidative and reductive peaks at 0.24 V and 0.16 V, respectively. Theefficacy of the electrode towards the concurrent detection of CRC was examined in the presence ofRiboflavin and Ascorbic acid. Detection of CRC by PArMCNTPS through differential pulse voltammetrytechnique was achieved from 2 × 10~(−7) M to 5 × 10~(−6) M and it presents adequately low detection(6.62 × 10~(−8) M) and quantification (2.20 × 10~(−7) M) limits. Furthermore the developed sensor wasemployed to determine CRC in turmeric powder to validate its analytical application.
