Abstract:
Electrochemical sensing of amaranth was performed by a voltammetric strategy in an aqueous solution. The paste electrode (PE) was modified with ۱-methyl-۳-butyl imidazolium bromide (MBIB) and Pt-CNTs nanocomposite and the MBIB/Pt-CNTs/PE was successfully used as a monitoring tool for sensing of amaranth. The MBIB/Pt-CNTs/PE accelerated the electron transfer in redox reaction of amaranth and improved its oxidation signal by about ۴.۸۲ fold. The MBIB/Pt-CNTs/PE measured this azo dye with a detection limit of ۱.۰ nM. In the final step, MBIB/Pt-CNTs/PE was employed for monitoring of amaranth drinking with an acceptable recovery data.
