An overview of recent advances in the detection of ascorbic acid by electrochemical techniques

Ascorbic acid is a water-soluble vitamin essential in human nutrition, an antioxidant, scavenger of free radicals biological systems, and cofactor several enzymes. The reference range for ascorbic healthy people 6 - 20 mg L-1. variable concentration within biology fluids was found clinical investigations to be metric assessing the exact amount oxidative stress body's metabolism. Electroanalytical techniques are group methods analytical chemistry, especially with extensive application pharmaceutical industries. These attracted further attention due their unique characteristics, such as reduced sample or solvent con­sumption, high analysis speed, low operating cost, sensitivity, which made them suitable candidates replacement supplementation spectrophotometry separation approaches. purpose this article scrutinize mechanisms applications current electroanalytical methods, including amperometric techniques, square wave voltammetry, differential pulse voltammetry cyclic detection acid.
