摘　　要：本工作通过制备一系列聚合物膜Ba^(2+)选择电极,比较了分别以不同的聚合物基体和增塑荆所组成的膜电极对Ba^(2+)的响应性能。其中聚合物基体为聚氯乙烯、氯化聚乙烯、EVA、聚醋酸乙烯酯、聚苯乙烯、醋酸纤维素,增塑剂为邻苯二甲酸二丁酯、邻苯二甲酸二辛酯、磷酸三丁酯。本文还讨论了聚合物的玻璃化转变温度和膜的均匀性对电极性能的影响。A series of polymer membrane Ba^(2+) selective electrodes were studied in this paper. The features of the electrodes with different polymer matrix and plasticizer which could response to barium ion were compared. The polyvinyl chloride, chlorinated polyethylene, ethylenevinylacteate, polyvinyl acetate, polystyrene, polyvinyl alcohol, cellulose acetate were used as matrix. The dioctyl phthalate, dibutyl phthalate and tributylphosphate were plasticizers. The influence of glass transition temperature and homogeneity of polymer membrane on the responding feature of electrodes were also discussed.
