Optimum performance was observed with a membrane composition (w/w) of A (6): PVC (40): DOP (56): NaTPB (1) for ionophore A and B (7): PVC (50): TMDP (86): NaTPB (1) for ionophore B. Membrane electrode A works satisfactorily in the concentration range of 1.0x 1 0-5 to 1.0x 1 0-1 M with a detection limit of 4.0xlO-6 M and Nernstian slope of 30.00.2 mY/decade. Meanwhile, membrane electrode B works in the concentration range of I.Ox 1 0-5 to 1.0x 1 0-1 M with detection limit 2.5xlO-6 M and Nernstian slope of29.IOA mY/decade. Both of these membrane electrodes exhibit wide pH range (4.0-5.0 and 6.0-10.0 for ligand A and 4.0-8.0 for ligand B) and posses a fast response time of below 20 s and also shelf life period of 3 months. The potentiometric selectivity coefficient values as determined by fixed interference method indicate excelIent selectivity for copper(II)ions over interfering cations. Both electrodes was used in the determination of copper(II) in waste water samples and the results were in agreement with an atomic absorption spectrometry method. 2014 thesis https://ir.upsi.edu.my/detailsg.php?det=1719 https://ir.upsi.edu.my/detailsg.php?det=1719 text eng N/A openAccess Masters Universiti Pendidikan Sultan Idris Fakulti Sains dan Matematik N/A |
