Embodiment Construction
[0032] The invention can complex various metal ions by using the structure of N-ethoxyacetoxy-N-picoline aniline, so that it can be used to realize the analysis of trace ion content. In the long-term research and development process, the applicant has extensively detected the metal ions that can be complexed by the compound structure of the present invention, and found that it is effective for Ca 2+ 、Cd 2+ 、Co 2+ 、Cr 3+ 、Cu 2+ , Fe 2+ , Fe 3+ , Hg 2+ 、K + , Mg 2+ , Mn 2+ 、Na + 、Ni 2+ , Pb 2+ , Zn 2+ and lanthanide metal ions have a certain binding ability, among which, especially have good complexing ability for zinc, cadmium, mercury, lead ions, the best is the remarkable and specificity for zinc ions The combined complexing ability can be used as an effective carrier for zinc ions. By introducing a chromogenic or fluorescent group at the para-position of the above-mentioned aniline structure, based on the principle of photoinduced electron transfer, when the io...
