Abstract :All solid-state contact PVC membrane electrodes for leadinsert ignore into journalissuearticles values(II); ion were developed by using dimethylene bisinsert ignore into journalissuearticles values(4-methylpiperidinedithiocarbamate); as neutral carrier and nitrophenyloctyl ether or dioctylsebacate as plasticizers. Response properties of the all solid-state contact PVC membrane electrode prepared with nitrophenyloctyl ether were better than those of the membrane electrode prepared with dioctylsebacate. The nitrophenyloctyl ether plasticized the all solid-state contact PVC membrane electrode and exhibited a good linear response of 30 mV/decade for leadinsert ignore into journalissuearticles values(II); ion within the concentration ranges \insert ignore into journalissuearticles values( 0.1-5\times10-6 \); mol dm\insert ignore into journalissuearticles values( -3 \); leadinsert ignore into journalissuearticles values(II); nitrate, good selectivity over alkali, alkali-earth and transition metal ions including copperinsert ignore into journalissuearticles values(II); ion by a factor of at least 10\insert ignore into journalissuearticles values( 3 \);, 10\insert ignore into journalissuearticles values( 4 \); and 10\insert ignore into journalissuearticles values( 2 \); respectively, and a short response time. The useful pH range was between 2.0 and 6.0.
