Abstract
A poly glutamic acid film modified electrode exhibited a catalytic response to
guanosine oxidation potential and higher peak current value. Linear concentration curve was
obtained in the concentration interval of 1.0 a 10.0 ?mol L-1 in 0.04 mol L-1 B-R buffer pH
2.0 with a detection limit of 0.198 ?mol L-1. The electrode was used for the determination of
guanosine in the potential of +1.1 V (vs. Ag/AgCl) using differential pulse voltammetry
(DPV) at urine sample with good recovery.
