摘要
A luminous intensity variation fluorescent probe (Probe 1) for the detection of ferric ion was developed. The quantitative range of Fe3+ content detected was 0-600 μM with the limit of detection at 0.76 μM. Furthermore, after 20 min of Fe3+ addition, the intensity of the luminescence of Probe 1 solution gradually decreased with increase in Fe3+ concentration. In addition, the B and G values of these images showed a linear relationship with Fe3+ concentration (0-500 μM). Probe 1 was successfully used for the rapid determination of Fe3+ concentration in real samples. This study demonstrates that Probe 1 is an excellent tool for the rapid determination of Fe3+ content in real samples using a smart phone without professional equipment.
