Automatic determination of ascorbic acid by flame atomic absorption spectrometry

Selective Electroanalysis of Ascorbic Acid Using a Nickel Hexacyanoferrate and Poly(3,4‐ethylenedioxythiophene) Hybrid Film Modified Electrode

“…Various analytical methods have been employed for the determination of ascorbic acid, such as spectrophotometry [14,15], spectrophotofluorimetry [16], atomic absorption spectrometry (AAS) [17], gas chromatography (GC) [18], and high-performance liquid chromatography (HPLC) [19]. The major drawbacks of these methods are that they are highly dependent on laboratory-based techniques that may require slow, and sometimes sophisticated, analytical methodologies [20].…”

Determination of Small Amounts of L-Ascorbic Acid Using the Chemiluminescence of an Iron-Chlorophyllin Complex

“…Until now, Lascorbic acid has been determined by many analytical methods. For example, determinations using atomic absorption, 4 flow injection, [5][6][7][8][9][10][11][12] electrochemiluminescence, 13 electrochemistry 14 and spectrophotometric analyses, [15][16][17][18] have been reported. [19][20][21][22][23][24][25] Moreover, as an L-ascorbic acid analysis using CL, the determination by flow injection with permanganate was reported.…”

An Automated Method for Determination of Ascorbic Acid in Urine by Flow Injection Chemiluminescence Coupling With on-Line Removal of Interference

“…Consequently, determination of ascorbic acid in foods, pharmaceuticals, and biological samples is crucial. A variety of methods have been employed for the determination of ascorbic acid in simple samples including foods, Vitamin C tablets and injections, among which iodometric method [1] is the official method, while fluorimetry, 2,3 atomic spectrometry, 4 spectrophotometry 5 and electroanalysis 6,7 have also been reported. For determination of AA in complex samples such as urine, various methods including spectrophotometry, [8][9][10][11] electroanalysis [12][13][14] and chromatography 15,16 have been reported.…”
