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 کاملPotentiometric Based Membrane Sensor for Zinc Ion
A PVC-based membrane of 12-crown-4 exhibits good response for Zn2+ in a wide concentration range (7.08 10-5-1.00 10-1 M) with a non-nernstian slope of 20.5 mv per decade of concentration of Zn2+. The response time of sensor is <10 s and the membrane can be used for more than 3 months without observing any divergence. In addition, the proposed sensor exhibits very good selectivity for Zn2+ o...
