Electrochemical investigation of oxytrol in fizzy drinks and juices via graphene and polymer printed PVC by ANOVA and design expert

Abstract

High dosages of oxytrol induce chronic as well as acute toxicity such as hallucination, irregular heartbeat, hoarseness, and coma. This study focused on novel PVC-printed polymer sensors and graphene sensors, which were synthesized to increase the surface area and sensitivity for oxytrol active material assessment. To evaluate the surface sensor structure, morphology, and elemental composition, scanning electron microscopy and energy dispersive X-ray spectroscopy were performed before and after measurement. At 25 ⁰C, the proposed printed-sensors operated efficiently throughout a wide concentration range of 1.0 × 10−7–1.0 × 10−2 mol L-1 response of 59 mV decade-1 with LOD of 5.0 × 10–8 M but carbon paste shows a slope of 58.98 mV decade-1 with LOD of 1.0 × 10–7 M. This response was over pH 2.5–7.5 within 7s and 8s for PVC-printed and carbon past respectively. The PVC printed sensors showed a lifetime of 70 days with acceptable repeatability using ANOVA single value. The proposed sensors exhibited strong selectivity towards oxytrol (I) ion over various valent-cations, including K(I), Cr(III), Mn(II), and other transition metals, as well as some sugars. The assessment of oxytrol achieved a high accuracy of 97.94–99.72% via the standard addition and calibration method. Additionally, comprise its concentration in samples, including canned drinks such as Coca-Cola, and natural juices like apple, berry, and pomegranate, using high-performance liquid chromatography (HPLC) outcomes and proposed method. The recovery percentages ranged from 98.00 to 99.27%, with satisfactory low standard and relative standard deviation values < 5, via statistical ANOVA, Design Expert for producing an ideal model with other parameters.
