The voltammetric and titrimetric determination of ascorbic acid levels in tropical fruit samples
The levels of ascorbic acid in 50 tropical fruit samples were determined by titrimetric method
using N-bromosuccinimide and also by cyclic voltammetry using a glassy carbon as working
electrode, Ag/AgCl as reference and platinum as the auxiliary electrode in 0.1 M phosphate
buffer, pH 2.0 containing 1mM Na 2 EDTA. The measurements were made in a potential
range of 200 mV to 1000 mV in relation to reference electrode using a scan rate of 50 mV/s.
