Acetylacetone, ethylacetoacetate and salicylaldehyde, are reported to form chelates with Cu of high stability as compared to other metals. Therefore, PVC based membranes of bis[acetylacetonato] Cu(II) (A), bis[ethylacetoacetate] Cu(II) (B) and bis[salicylaldehyde] Cu(II) (C) were studied as Cu(II) selective sensors. The addition of Na tetraphenylborate and various plasticizers, viz., DOS, TEHP, DOP, DBP and TBP substantially improve the performance of the sensors. The membranes of various compositions of the three chelates were studied and the best performance was obtained for the membrane A (1%): PVC (33%): TBP (65%): NaTPB (1%). The sensor shows a linear potential response to Cu(II) over wide concentration range 2.0 × 10-6 to 1.0 × 10-1 M (detection limit ∼0.1 ppm) with Nernstian compliance (29.3 mV decade-1 of activity) between pH 2.6 and 6.0 with a fast response time of ∼9 s. The potentiometric selectivity coefficient values as determined by match potential method (MPM) indicate excellent selectivity for Cu2+ ions over interfering cations. The sensor exhibits adequate shelf life (∼3 mo) with good reproducibility (S.D. ±0.2 mV). The sensor was used in the potentiometric titration of Cu2+ with EDTA. The utility of the sensor was tested by determining Cu in vegetable foliar and multivitamin capsule successfully.
