| Özet |
| In this study, all-solid-state contact PVC membrane silver(I)-selective sensor has been prepared and 5,10,15,20-tetra(4-pyridyl)-21H,23H-porphine used as ionophore. Optimum membrane composition; 3.5% ionophore, 59.6% Bis(2-ethylhexyl) sebacate (BEHS), 1.0% potassium tetrakis (p-chlorophenyl) borate (KTpClPB) and 35.9% polyvinyl chloride (PVC). The developed silver(I)-selective sensor exhibited a linear response (E = −51,57 (−log[Ag+]) + 1690,6 and R2 = 0,9986) in the varying concentration range of 1.0 × 10−1 to 1.0 × 10−5 mol L−1 silver ions. The limit of detection of the sensor was calculated as 1.9 × 10−6 mol L−1. The silver(I)-selective sensor exhibited good selectivity towards some alkali, alkali earth and heavy metal ions. The sensor can be used in the pH range from 4.0 to 10.0. The sensor has been shown to have good reusability and response time less than 8 s. The sensor was … |
