| Abstract: | A series of polymer membrane Ba2 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, ethylene-vinylacteate, 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. |
