| dc.description | tA novel Schiff base (L1) derivative from cinnamaldehyde with a simple structure was synthesized andevaluated as a sensitive colorimetric Ni2+sensor in aqueous solution. Addition of nickel dissolved inwater into a L1 solution produced a rapid color change from faded yellow to deep orange, correspondingto a large red shift in the absorption peak from 435 to 480 nm. L1 exhibited a detection limit for Ni2+inwater of 1 × 10−7M measured by absorption spectroscopy, whereas by naked eye the detection limit wasof the order of 5 × 10−6M. Interaction between L1 and other biologically and environmentally relevantmetal ions such as Hg2+, Pb2+, Co2+, Cu2+and Mn2+, induced minimal spectral changes. These results showthat the Schiff base L1 could be an excellent Ni2+chemosensor with high metal selectivity and with thecapability to perform the detection in water over a pH range of 5.5–8. | |
