Abstract :
electrochemical sensing of amaranth was performed by a voltammetric strategy in an aqueous solution. the paste electrode (pe) was modified with 1-methyl-3-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 4.82 fold. the mbib/pt-cnts/pe measured this azo dye with a detection limit of 1.0 nm. in the final step, mbib/pt-cnts/pe was employed for monitoring of amaranth drinking with an acceptable recovery data.
