摘要
参照文献以1,2-二(4H-1,2,4-三唑)乙烷为配体与CdCl_(2)在室温下合成了具有阳离子框架配位聚合物1,以粉末衍射证实了配合物1被成功制备。研究了配合物1对Cr_(2)O_(7)^(2-)的吸附,结果表明当配合物1与Cr_(2)O_(7)^(2-)的物质的量比为1∶1,2∶1和4∶1时,在1 h内的吸附率分别为6%,18%和49%。同时研究还表明其他阴离子对吸附Cr_(2)O_(7)^(2-)除PO_(4)^(3-)外基本没有干扰,Cr_(2)O_(7)^(2-)@配合物具有缓释现象。
Referring to the literature,a cationic framework coordination polymer 1 was synthesized using 1,2-bis(4H-1,2,4-triazole)ethane as a ligand and CdCl_(2) at room temperature.The successful synthesis of complex 1 was confirmed by powder diffraction.The adsorption of Cr_(2)O_(7)^(2-)by coordination polymer 1 was studied,and the results showed that when the molar ratios of 1 to Cr_(2)O_(7)^(2-)were 1∶1,2∶1 and 4∶1,the adsorption rates within 1 h were 6%,18%,and 49%,respectively.At the same time,the study also indicates that other anions have little interference on the adsorption of Cr_(2)O_(7)^(2-)except for PO 43-and the Cr_(2)O_(7)^(2-)@complex exhibits a slow-release phenomenon.
