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...

Abstract

The invention discloses an organic compound for detecting content of metal ions. The organic compound for detecting the content of the metal ions uses N-ethoxyacetic acid-N-methyl pyridine aniline asa metal ion complex; a chromophore or fluorophore is introduced into a molecule of the compound to generate a color indicator or a fluorescence indicator of metal ions, particularly zinc ions. The organic compound for detecting the content of the metal ions, disclosed by the invention, has the advantages that the compound can also be fixed on a hydrophilic polymer; by using the chromophore or thefluorophore, the compound can be prepared into a reversible metal ion fluorescent probe capable of being used for multiple times; the compound can be suitable for continuous detection of metal ion concentration in various environments, particularly for continuous detection of zinc ion concentration in the water.

Description

technical field [0001] The invention belongs to the field of organic compounds, and in particular relates to an organic compound which can be used for detecting the content of metal ions in water and related applications. Background technique [0002] Water is an indispensable natural resource for human development, and also the material basis for the survival of human beings and all living things. With the rapid development of my country's economy, people rely too much on the input of water resources, resulting in a large amount of waste of water resources and water pollution. The demand for water for industry, agriculture, and residents' daily life has greatly increased. In some cities, water consumption exceeds the water supply capacity of local water resources, and urban water shortages. In particular, the diversification of industrial development and complex pollutants lead to aggravated water pollution. Facing the serious shortage and pollution of water resources, we...
