Two Fold Amplification of Paste Electrode with Pt/Graphene Nanocomposite and Room Temperature Ionic Liquid to Monitoring of Vitamin B6 in Environmental and Food Samples
A new highly sensitive and powerful electroanalytical tool fabricated by two fold amplification of paste electrode (PE) with Pt/graphene nanocomposite (Pt/Gr-NC) and room temperature ionic liquid (1-Hexyl-3-methylimidazolium hexafluorophosphate (1H3MTIHFP) in this case) (Pt/Gr-NC/1H3MTIHFP/PE) for detection and determination of vitamin B6 in environmental and food samples. The modification with a synergistic effect in the designed sensor has caused the vitamin B6 signal to increase greatly, and the conditions for designing an ultra-sensitive sensor for the measurement with linear range 0.004–250 µM and the detection limit 0.5 nM created. On the other hand, this synergistic effect (1H3MTIHFP and Pt/Gr-NC) due to presence of has caused the vitamin B6 oxidation signal to improve about 4.9 times and its oxidation potential to decrease by 140 mV, which means creating a sensor with high selectivity and suitable detection limit. Finally, Pt/Gr-NC/1H3MTIHFP/PE was used as a perfect analytical tool in monitoring of real samples such as fruit juices and water. Results was completely confirm ability of Pt/Gr-NC/1H3MTIHFP/PE in sensing vitamin B6.
期刊介绍：
Topics in Catalysis publishes topical collections in all fields of catalysis which are composed only of invited articles from leading authors. The journal documents today’s emerging and critical trends in all branches of catalysis. Each themed issue is organized by renowned Guest Editors in collaboration with the Editors-in-Chief. Proposals for new topics are welcome and should be submitted directly to the Editors-in-Chief.
The publication of individual uninvited original research articles can be sent to our sister journal Catalysis Letters. This journal aims for rapid publication of high-impact original research articles in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
