Preparation of luminescent crystal material for selectively detecting dichromate ions

The invention discloses preparation of a luminescent crystal material for selectively detecting dichromate ions. The method comprises the steps of adding 4-amino-3,5-bis(imidazole methyl)-1,2,4-triazole(3-abit) and zinc acetate to an aqueous solution and stirring to obtain a stable suspension; adding 2,5-thiophenedicarboxylic acid (2,5-tdc) to the suspension and stirring to prepare a stable suspension; putting the suspension into a closed polytetrafluoroethylene reaction kettle for heating reaction, slowly cooling and then filtering, washing and drying to obtain the luminescent crystal material {[Zn(2,5-tdc)(3-abit)].H2O}n. The method has the advantage that the luminescent crystal material {[Zn(2,5-tdc)(3-abit)].H2O}n for efficiently and selectively detecting the dichromate ions is obtained. 本发明公开了种具有选择性探测重铬酸根离子的发光晶体材料的制备。将4-氨基-3,5-二(咪唑甲基)-1,2,4-三氮唑(3-abit)和乙酸锌加入到水溶液中搅拌制得稳定悬浮液；将2,5-噻吩二羧酸(2,5-tdc)加入到上述悬浮液中搅拌制得稳定悬浮液，将该悬浮液置于密闭的聚四氟乙烯反应釜中加热反应，缓慢降温后经过滤、洗涤、干燥即得到发光晶体材料{[Zn(2,5-tdc)(3-abit)]·HO}。本发明的优点为：获得种具有高效选择性探测重铬
