摘　　要：实验比较了多种膜组分的性能 ,制得了有较长使用寿命的三氟乙酰对癸基苯为载体的 PVC膜碳酸根离子电极。适当增大膜中载体的含量 ,采用亲脂性强的增塑剂并加入适量增水性溶剂 ,有利于延长电极的使用寿命和增强抗亲脂性阴离子干扰的能力。已利用此种膜电极 ,以控制 p H标准比较法测定了模拟血清和质控血清中的碳酸根 。PVC membrane carbonate ion electrode with trifluoroacetyl p decylbenzene (TFADB) as neutral ionosphere.Tridodecylmethylammonium chloride (TDMACL)as active, and didecylphthalate+dibenzyl ether (DDP+DBE) as plasticizing solvent was prepared and its lifetime in the continuous monitoring system was longer than three months.Determination of carbonate in a series of model serum samples and aqueous solutions samples by the methods of the control pH and known dilution-standard addition has been developed.
