	1	Electrochemical Preparation of Poly(arginine)-Modified Carbon Nanotube Paste Electrode and its Application for the Determination of Pyridoxine in the Presence of Riboflavin: An Electroanalytical Approach显示文摘A simple poly(arginine)film-modified carbon nanotube paste electrode(PAMCNTPE)was prepared using cyclic voltam-metry(CV).The devised sensor was subjected to field-emission scanning electron microscope(FESEM)and CV charac-terization.The sensing of 0.1 mM pyridoxine(PY)was upgraded at PAMCNTPE as compared to the bare carbon nanotube paste electrode(BCNTPE).The PAMCNTPE detects the 0.1 mM PY at a specific potential 0.727 V with a current response of 10.68μA.In the case of BCNTPE,the PY appeared at 0.798 V with a current 2.90μA.The proposed analytical method was optimized by prime parameters such as the impact scan rate,pH and PY concentration.Under optimal conditions,the concentration of PY is directly proportional to oxidation current(I_(pa))in linear range 2-10μM,and 10-80μM with a detection limit(LOD)of 9.6×10^(−7) M and limit of quantification(LOQ)of 3.21×10^(−6) M.The simultaneous determination,concen-tration variation analysis of PY is performed with riboflavin(RF)and interference analysis in detecting PY also examined.The proposed sensor was effectively applied for the determination of PY in natural food supplement with excellent recovery.
