中文摘要:

      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pH标准比较法测定了模拟血清和质控血清中的碳酸根，并以已知稀释－标准加入法测定了碳酸盐型卤水中的碳酸根。

英文摘要:

      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.
