Polymeric Membrane Sensor for Potentiometric Determination of Tin(II) Ions
Tin(II)-ion-selective electrode consisting of dibenzo-18-crown-6 (DB18C6) as an ionophore inPVC matrix was developed. The influences of membrane composition, selectivity, response time,reversibility and temperature on the electrode performance were investigated. The electrodeshowed a near Nernstian response for Sn2+ ions over a concentration range from 1.0× 10-6 – 1.0× 10-2 M with a slope of 27...
متن کاملA PVC plasticized sensor for Ni(II) ion based on a simple ethylenediamine derivative.
A new PVC membrane ion selective electrode which is highly selective towards Ni(II) ions was constructed using a Schiff base containing a binaphthyl moiety as the ionophore. The sensor exhibited a good Nernstian response for nickel ions over the concentration range 1.0x10(-1)-5.0x10(-6) M with a lower limit of detection of 1.3x10(-6) M. It has a fast response time and can be used for a period o...
متن کاملInvestigation of interfering ions effect on a gadolinium(III) PVC membrane sensor
A PVC-membrane ion-selective electrode was constructed for quantitative monitoring of gadolinium(III) ion based on 3-methyl-1H-1,2,4-triazole-5-ylhydrosufide (MTY) as an ion carrier. The electrode performance includes a Nernstian slope of 19.8 ± 0.4 mV per decade across a wide concentration range between 1.0 × 10 and 1.0 × 10 M and a detection limit of 7.3 × 10 M. The best performance was obtai...

متن کاملRelaxation of Molecular Conformation of Plasticized Poly (vinyl Chloride) (pvc)
The relaxation by creep recovery of plasticized poly lvinyl chloride) (PVC) was tested in relation to applied stresses and working temperatures. The relaxation time increased with stress but decreased with temperature. From the temperature dependence of relaxation times, an energy of 0.21 eV was found to activate the creep recovery process. It is thought that creep recovery is effected by the c...
