Abstract
A method is developed for the flow-injection amperometric determination of tryptophane and pyridoxine on a screen-printed electrode with electrodeposited gold nanoparticles. The dependence of the analytical signal on the concentrations of tryptophane and pyridoxine on the logarithmic coordinates is linear in the ranges from 5 × 10−7 to 5 × 10−3 and from 5 × 10−8× to 5 × 10–3 M, respectively. A possibility of the simultaneous amperometric determination of tryptophane and pyridoxine on a dual screen-printed electrode modified by gold nanoparticles in a flow-injection system is shown. The developed method is approved in the determination of tryptophane and pyridoxine in medicinal preparations.
