摘　　要：研究了基于2,4-二羟基苯甲醛缩硫脲合镍(II)为载体的溶剂聚合膜阴离子敏感电极,该电极对高氯酸根离子(C1O-4)的电位响应具有优良的选择性和灵敏度。在pH=5.0的缓冲溶液中,电极电位呈近能斯特响应,线性响应范围为3×10-6—10-1mol/L,斜率为-52.8mV/dec,检测下限为6×10-7mol/L,该电极响应时间短,且具有良好的稳定性和重现性。A solvent polymeric membrane anion-sensitive based on Ni-schiff base complexes as the neutral carrier is reported. The electrode exhibits unique selectivity and high sensitivity toward perchlorate ion. It gives linear response over the concentration range 3×10-6—10-1mol/L and a response slope of -52.8mV/dec. in buffer solutions of pH5.0.The electrode displays fast response,Stability and repeatability.
