Voltammetric determination of tryptophan in the presence of uric acid and dopamine using carbon paste electrode modified with multi-walled carbon nanotubes
A carbon paste electrode modified with multi-walled carbon nanotubes (CPE-MWCNTs) was prepared for determination of tryptophan (Trp) in the presence of uric acid (UA) and dopamine (DA). Cyclic voltammetry, chronoamperometry and differential pulse voltammetry (DPV) techniques were used to investigate...
