A novel, exceptionally simple and rapid method has been developed for visual detection of L-glutamic acid (Glu) in aqueous solution. The chemosensor employed is easy to prepare and use with an added advantage of cost effectiveness. It exhibits an excellent selectivity and sensitivity towards Glu over other amino acids by changes in both absorption intensity and colour intensity. The chemosensor provides a fast response time, with an LOD of about 7.96 × 10−7 M suggesting that the chemosensor may be useful as a valuable practical sensor for environmental analyses of glutamic acid.
