Fabrication of a disposable electrode based on recordable gold compact disc modified with Bi-Bi2O2CO3@ graphitic carbon nitride nanocomposite for the simultaneous detection of mesalazine and uric acid in biological fluids
A homemade disposable gold electrode was fabricated from gold compact disc (Au-CDs) and modified with Bi-Bi2O2CO3@g-C3N4 nanocomposite for the simultaneous detection of mesalazine (5-amino salicylic acid; 5-ASA) and uric acid (UA) in aqueous solutions. The Bi-Bi2O2CO3@g-C3N4 nanocomposite was characterized by Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, field emission scanning electron microscopy and photoluminescence spectroscopy. The analytical response of the modified g-CDs electrode towards 5-ASA and UA was evaluated by cyclic voltammetry and differential pulse voltammetry. Under optimal conditions, the modified g-CDs electrode was able to detect 5-ASA and UA in the concentration ranges of 1.0-160 µmol L-1 and 10-190 µmol L-1 with detection limits of 0.65 µmol L-1 and 3.07 µmol L-1 for 5-ASA and UA, respectively. The prepared Bi-Bi2O2CO3@g-C3N4 nanocomposite exhibited high sensitivity and selectivity towards 5-ASA and UA in urine and plasma samples with recoveries in the range of 91.0% - 109.3%.
期刊介绍：
The Journal of Alloys and Compounds is intended to serve as an international medium for the publication of work on solid materials comprising compounds as well as alloys. Its great strength lies in the diversity of discipline which it encompasses, drawing together results from materials science, solid-state chemistry and physics.
