Abstract

The invention discloses a preparation method of a luminous crystal material capable of selectively detecting Fe<3+> ions. 4-amidogen-3,5-di(3-pyridyl)-1,2,4-triazole (3-abpt) and zinc nitrate hexahydrate are added into a mixed solution of acetonitrile and N,N'-dimethyl formamide to be stirred to be prepared into a solution; 1,4-naphthalic acid (1,4-ndc) is added into the prepared solution to be stirred until the solution is clear; the solution is put into a sealed reaction kettle for heating reaction for three days; after the temperature is slowly lowered, filtering, washing and drying are performed to obtain the luminous crystal material {[Zn2(1,4ndc)2(3abpt)].H2O}n. The preparation method has the advantage that the luminous crystal material {[Zn2(1,4ndc)2(3abpt)].H2O}n capable of efficiently and selectively detecting the Fe<3+> ions is obtained.

Description

[0001] a technical field [0002] The invention relates to the preparation of metal cation detection materials, in particular to a selective detection of Fe 3+ Preparation method of ionic luminescent crystal material. [0003] Two background technology [0004] Iron is the most abundant trace metal element in the human body. It is also an important component of hemoglobin and an important element for transporting and exchanging oxygen in the blood. It is closely related to human health. Both iron deficiency and iron excess will affect human health and cause diseases, such as hemochromatosis, anemia, liver function damage, diabetes, heart failure and Parkinson's disease. At the same time, with the rapid development of society and industry, iron has become the metal material most used by human beings. It is widely used in various fields of social production and life, and plays an irreplaceable role in the development of the national economy and industry. However, While bringing...
