چکیده
A characteristic redox potential-time curve of the iron(II)/nitric acid autocatalytic reaction was applied to a time measurement-determination for sub-microM levels of folic acid. The determination range was 7.5 x 10(-7) - 1.5 x 10(-5) M, the detection limit (3 sigma) was 5.9 x 10(-7) M, and the relative standard deviation was 3.6% (n = 5).
