Abstract

The present invention discloses 1, 3-bi (2-benzothiazolyl diazo amino) benzene (BBTAB) as one kind of diherocyclic triazene compound and its preparation process and application. The compound is prepared with m-phenylenediamine and through double diazonation and coupling with 2-amino benzothiazole. Inside alkali medium with beta-CD, the diherocyclic triazene structure of the reagent is compounded with copper ion to raise the rigidity of BBTAB and to strength the fluorescence obviously. Based on water has been said, new fluorescent analysis method of determining Cu (II) with BBTAB is established. Test on different water samples containing copper ion gives satisfactory results. In addition, BBTAB may be also used as developing agent.

Description

technical field

[0001] The invention relates to a bistriazene compound, especially a compound containing a diheterocyclic triazene structure, a preparation method thereof, and an application thereof. Background technique

[0002] After the triazene structure is deprotonated, it is easy to coordinate with transition metal ions and is a good coordination group (J.Barker, N.D.Cameron, M.Kilner, et al, J.Chem.Soc.Dalton Trans., 12( 1991) 3435.). Triazene reagent is an excellent color developer for metal ions such as cadmium, mercury, copper, nickel, silver, etc., because of its high sensitivity and easy synthesis, it is constantly attracting people's attention, but its coexisting ions interfere greatly. The performance needs to be improved, and it is often only used as a chromogenic agent for photometric analysis, and rarely used as a coordination structure of a fluorescent reagent for the fluorescence detection of metal ions. Bistriazene reagents are more sensitive than gener...
