| Abstract: | he voltammetriy of piperine at
TBP chemically modified electrode has been studied. A welldefined derivative peak is obtained
at 1.40 V(vs.SCE) in Britton-Robinson buffer solution(pH4.6). The peak current is proportional to
the concentration of piperine in the range of 7.410-92.210-7mol/L. The detection limit has been
estimated as 2.210-11mol/L with 6 min accumulation. The method has been applied to
determine piperine in natural pepper with satisfactory results. |
