摘要: A simple differential pulse voltammetric method based on a graphite paste electrode (GPE) was developed for the quantitative determination of folic acid (FA) in tablets. The exhibits clear improve- ment current response. linear response electroanalytical approach exists from 4.97 � 10 6 to 2.94 5 mol L 1 with limit detection about 2.67 KCl solutions. procedure tested by recovery studies and compared spec- trophotometric chromatographic methods. re- sults are described discussed light existing literature.
