Performance Evaluation of a Novel Potentiometric Membrane Sensor for Determination of Atorvastatin in Pharmaceutical Preparations
A novel potentiometric ion-selective PVC membrane sensor for analysis of atorvastatin (AT) in pharmaceutical preparations based on atorvastatin-(tetraphenyl borate), (AT-(TPB)2) as sensing element, tetraphenyl borate as additive and tris-2-ethyl-hexyl phosphate (TOP) as plasticizer solvent was prepared. The electrode shows a good Nernestian response over the concentration range of 0.09–5586 µ...

متن کاملNovel imidazole PVC-based sensor based on a thiopyrilium compound.
A novel imidazole membrane sensor based on 2,4,6-triphenyl thiopyrilium perchlorate (TTP) as an excellent charged carrier, poly(vinyl chloride) (PVC), the plasticizer dibutyl phthalate (DBP) and oleic acid as an additive is described. The sensor responds to imidazole over a wide concentration range from 1.0 x 10(-5) to 1.0 x 10(-1) M with a slope of +33.5 +/- 0.5 mV per decade. The detection li...
متن کاملDesign novel optical sensor for determination of bismuth based on immobilization of 4-(4-nitrophenyl)-1-naphthol on a triacetylcellulose membrane
A novel optical sensor has been proposed for sensitive determination of bismuth ion basedon immobilization of 4-(4-nitrophenylazo)-1-naphthol on a triacetylcellulose membrane.Chemical binding of bismuth ions in solution with a 4-(4-nitrophenylazo)-1-naphtholimmobilized on the triacetylcelluse surface could be monitored spectrophotometrically. Theoptode shows excellent response over wide concent...
متن کاملEnzymatic Conductometric Biosensor Based on PVC Membrane Containing Methyl Viologen/Nafion®/Nitrate Reductase for Determination of Nitrate in Natural Water Samples
A highly sensitive, fast, and stable conductometric enzyme biosensor for the determination of nitrate in water is described and validated in natural water samples. The nitrate biosensor is based on a methyl viologen mediator mixed with nitrate reductase (NR) from Aspergillus niger and Nafion® cation-exchange polymer dissolved in a plasticized PVC membrane deposited on the sensitive surface of i...
