Enhanced Ni 2+ /Ni 3+ redox activity in dopant-free nickel-based metal–organic framework for sensitive electrochemical detection of methanol in beverages
Abstract
with a linear range from 0.5 to 11 µM. These findings illustrate that the Ni-MOF material would be a viable electrochemical sensing platform for VOCs. The sensor allows indirect detection of methanol in real samples, such as natural and artificial beverages. The recoveries were 95-107% with spiked sample analysis, which showed excellent analytical reliability and a low degree of matrix effects. In general, the proposed work demonstrates the possibilities of applied methanol monitoring in food and drink safety sectors, supporting human health protection.
