摘　　要：以1,5-二苯基缩二氨基脲为载体,制备了PVC膜铝离子选择电极,并对电极的性能进行了测试.结果表明:电极的能斯特响应斜率为21.6 mV/decade,检测下限为4.4×10-7mol/L,线性范围为10-6～10-2mol/L,电极具有良好的稳定性和重现性.将该电极用于实际样品中铝离子的测定,结果令人满意.An aluminium（Ⅲ） ion-selective polyvinyl chloride（PVC） membrane electrode based on 1,5-diphenylcarbazone was prepared and its electrode behavior was evaluated.The electrode exhibited a linear response to the aluminium（Ⅲ） in the concentration range of 10-6~10-2 mol/ L with slope of 21.6 mV/decade and with the detection limit of 4.4×10-7 mol/L.The electrode had good stability and reproducibility.The electrode was used for the determination of aluminium content and satisfactory results were obtained.
