UV/Vis absorption spectroelectrochemistry of folic acid

Abstract UV/Vis absorption spectroelectrochemistry is a very promising analytical technique due to the complementary information that simultaneously obtained from electrochemistry and spectroscopy. In this work, used in parallel configuration study oxidation of folic acid alkaline medium. Herein, has been detect both products consumed at electrode/solution interface, allowing us develop an protocol quantify vitamin B9 pharmaceutical tablets. Linear ranges three orders magnitude have achieved basic medium (pH = 12.9), obtaining high repeatability low detection limits. The spectroelectrochemical determination tablets pH values particularly interesting because changes occur optical signal during electrochemical FA, providing results with good figures merit demonstrating utility versatility hyphenated technique, spectroelectrochemistry.
