“…The flavin nucleotide has the unique ability to transfer one or two electrons. So far several analytical techniques such as HPLC [3], chemiluminescence [4], spectroelectrochemical [5], fluorescence [6], and capillary electrophoresis [7] have been devised for the determination of Riboflavin. However, these methods are usually tedious, time consuming and involve complicated procedures and expensive instrumentation.…”

“…3A because of the catalytic decomposition of peroxymonosulfate, so it was no necessary to set up mixing tube and PMS and Co(II) was mixed at the input of the flow CL analyzer, which was a little different from our previous researches [17,18]. The CL intensity decreased slightly with the flow rates of the reagent solutions in the range of 0.5-2.5 mL min −1 from Fig.…”

Based on the chemiluminescence (CL) phenomena of folic acid in peroxomonosulfate-cobalt(II) system, a rapid and sensitive CL method was developed for determination of folic acid in pharmaceutical preparations and its urinary metabolism processes. Under the optimum conditions, the relative CL intensity was linear over the concentration ranging from 10 −9 to 8 × 10 −7 mol L −1 (R 2 = 0.9991) with a detection limit as low as 6 × 10 −10 mol L −1 (S/N = 3) and relative standard deviation was 2.63% for 2 × 10 −8 mol L −1 folic acid (n = 11). This method has been successfully applied to the determination of folic acid in tablets and human urine. The blank CL emission was yielded owing to the formation of singlet oxygen molecular pair from the quenching experiment of 1,4-diazabicyclo[2.2.2]octane, and pterine-6-carboxylic acid might be the degradation intermediate in this system and it also acts an energy acceptor and sensitizes the chemiluminescence based on the studies of the CL and fluorescence spectra.

“…Thus, determination of VB2 is very significant in monitoring the amount of VB2 in vitamin drugs. Currently, different methods and techniques have been used to determine concentration of VB2, including chemiluminescence [3][4], chromatography [5][6][7], voltammetry [8], fluorescence [9], flame atomic absorption spectrometry [10], and combination of these methods [11][12][13]. But these methods are not only sophisticated but nonspecific, worse still, some expensive and broad-scale equipments are needed.…”

Under the condition of weak acidity of pH 5.2, a sensitive vitamin B2 electrochemical sensor based on molecularly imprinted nonconducting polymer of o-aminophenol by potentiostatic polymerization in the presence of template(vitamin B2) on a glassy carbon electrode was prepared, and its performance was studied. The sensor exhibited good sensitivity and selectivity to VB2. The detection limit went down to 2.3851nM, and a linear relationship between the current incremental and the concentration was found in the range of 10～120nM. And the sensor could use in detection of VB2 real sample for a long time and show good reproducibility. The average recovery rate to VB2 was 98.41%.
