PENGARUH KOMPOSISI MEMBRAN BERBASIS PVC MENGGUNAKAN IONOFOR 1,10, DIAZA, 18-CROWN-6 TERHADAP KINERJA ELEKTRODA SELEKTIF ION (ESI)- Pb(II)
Abstract
The effect of PVC (Polyvinylchloride)-Based Membrane Composition to Ion Selective Electrode (ISE)-Pb(II)Performance using Ionophore1.10, Diaza, 18-Crown-6, Plasticizer NPOE (Nitrophenyl Octhyl Ether), Anionic SiteKTCPB (Potassium Tetrakis (4-chloro phenyl) borate) have been performed. The study is aimed at designing selectiveelectrode ions for lead in a polymeric PVC membrane electrode. The PVC membrane is made with a total compositionof PVC, NPOE, ionophore and KTCPB is 100 mg diluted with tetrahydrofuran. Ion Selective Electrode is made byimmobilizing the ionophore into the PVC polymer. Result of research obtained two compositions that give goodresponse to ion Pb that is at composition 30:60.6:4 with nernst factor is 23,3 (R = 0,979), range of measurement is 1 x10-5 M – 1 x 10-1 M and at composition with nernst factor is 30:58.8:4 26,15 (R = 0,830), range of measurement is 1 x10-3 M – 1 x 10-1 M.References
