Determination of ascorbic acid in different citrus fruits under reversed phase conditions with UPLC
This study compared the concentration of ascorbic acid between citrus fruits collected from the farm of Kerman in Iran. Determination of ascorbic acid was carried out using a liquid chromatography coupled to a diode array detector, with reverse phase and isocratic elution. The validation parameters showed efficiency, adequate linearity, relative standard deviation values 0.02 % (n=10) for repea...

متن کاملElectrochemical Sensor for Determination of Ascorbic Acid Using a 2-Chlorobenzoyl Ferrocene/Carbon Nanotube Paste Electrode
A chemically modified carbon paste electrode with 2-chlorobenzoyl ferrocene (2CBF) and carbon nanotube (2CBFCNPE) was employed to study the electrocatalytic oxidation of ascorbic acid in aqueous solution using cyclic voltammetry, square wave voltammetry and chronoamperometry. The diffusion coefficient (D = 1.42 × 10-6 cm2 s-1), and the kinetic parameter such as ...
متن کاملPlatinum Nanoparticle Electrode Modified Iodine using Cyclic Voltammetry and Chronoamperometry for Determination of Ascorbic Acid
This study investigated the oxidation of ascorbic acid (Vitamin C) using a platinum nanoparticle electrode coated with an iodine monolayer, called a modified electrode. The electrode were grown using the cyclic voltammetry technique and the electrochemical measurements were taken using the cyclic voltammetry and chronoamperometric technique. In the case of platinum nanoparticle electrode modifi...
متن کاملSimultaneous Determination of Ascorbic Acid and Free Malondialdehyde in Human Serum by HPLC–UV
required for the prevention of deficiency diseases such as scurvy, it also might be useful for reducing the risk of developing chronic diseases such as cancer, cardiovascular disorders, and cataracts. The protective mechanism probably is due to the antioxidant effect of ascorbic acid (10). Therefore, applications of various detection systems and analytical procedures for the separation of ascor...
