Resumo
Primaquine, an antimalarial drug, presents a well-defined oxidation peak around +0.6V vs SCE at a glassy carbon electrode that can be used for its determination. Calibration graphs were obtained for primaquine in B-R buffer pH 4.0 from 3.00 x 10(-5) mol L-1 to 1.00 x 10(-2) mol L-1 using linear-scan voltammetry and 3.00 x 10(-5) mol L-1 to 1.00 x 10(-2) mol L-1 using differential pulse or square-wave voltammetry. The correspondent detection limits was 9.4 mu g mL(-1); 4.2 and 1.8 mu g mL(-1), respectively. All the voltammetric methods were applied with success in direct determination of the primaquine in commercial tablets without separation or extraction procedures.
