Abstract :All solid-state contact PVC membrane electrodes for lead(II) ion were developed by using dimethylene bis(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 lead(II) ion within the concentration ranges \( 0.1-5\times10-6 \) mol dm\( -3 \) lead(II) nitrate, good selectivity over alkali, alkali-earth and transition metal ions including copper(II) ion by a factor of at least 10\( 3 \), 10\( 4 \) and 10\( 2 \) respectively, and a short response time. The useful pH range was between 2.0 and 6.0.Keywords : All solid-state contact, lead(II) ion-selective membrane electrode, Dimethylene bis(4-methylpiperidinedithiocarbamate) Ionophore.
