| Özet |
| A PVC membrane Sn(II)-ion-selective electrode has been constructed using dibenzo-18-crown-6 (DB18C6) as membrane carrier. The sensor shows a near Nernstian response for Sn(II) ions over a concentration range from 1.0 × 10-6 to 1.0 × 10-2 M with a slope of 27.5 ± 0.6 mV per concentration decade in an acidic solution (pH = 1). The limit of detection was 8.0 × 10-7 M. It has a response time of <15 s and can be used for at least 3 months without any divergence in potentials. The proposed membrane electrode revealed very good selectivity for Sn(II) ions over a wide variety of other cations and could be used in acidic media. The isothermal temperature coefficient of this electrode amounted to 0.0012 V/°C. The stability constant (log K |
