研制了新型联萘冠醚修饰电极.对分别以二联萘-22-冠-6、联萘-20-冠-6等五种新型冠醚修饰的电极性能进行了比较,并对利用此修饰电极测定环境水中汞作了初步探讨.以二联萘-22-冠-6制备的修饰电极,采用阳极溶出伏安法测汞,最低检出限为1×10~(-8)M.
A new type of binocular crown ether modified electrode was developed.Compared with five novel crown ethers modified by binaphthyl-22-crown-6 and binaphthyl-20-crown-6 respectively, Electrode was used to determine mercury in environment water.A modified electrode prepared with binaphthyl-22-crown-6 was used for the determination of mercury by anodic stripping voltammetry with the detection limit of 1 × 10 -8 M.
