Abstract

The invention relates to a preparation method and application of a magnetic pyrenebutyric acid fluorescent probe detecting ferric ions, and belongs to the technical field of novel functional materials and analytical chemistry. Ferroferric oxide has high magnetism, 1-pyrenebutyric acid has good fluorescent performance, when ferroferric oxide and 1-pyrenebutyric acid are composited, magnetism of ferroferric oxide can be kept, the fluorescent performance of 1-pyrenebutyric acid can be kept as well, and therefore detection and separation of ferric ions can be achieved, the detection limit used for analyzing ferric ions is 0.01 mmol / L, and the linear range ranges from 0.5 mmol / L to 300 mmol / L.

Description

technical field [0001] The invention relates to a preparation method and application of a magnetic pyrene butyric acid fluorescent probe for detecting ferric ions, and belongs to the technical field of new functional materials and chemical analysis. Background technique [0002] Fe 3+ Not only is it a heavy metal ion, but it is also one of the most important trace elements in the human body. It is present in many enzymes and proteins and acts as a cofactor for cellular metabolic reactions. Fe 3+ Blood can promote the formation of hemoglobin, and iron deficiency can cause anemia in people. However, excessive iron content can damage biological systems because its redox form catalyzes the production of highly reactive oxygen species that are involved in diseases such as Parkinson's disease, Alzheimer's disease and cancer. Therefore, the determination of the content of iron ions in the human body is a very important issue. [0003] Fluorometric assays have become one of th...
