A nickel(II) selective all-solid-state PVC membrane sensor (ASS-PMS) has been designed and constructed for the monitoring of nanomolar nickel(II) concentrations in various samples. The applicability of the sensor to real samples was proved through its use for the anal. of the target ion in waste water samples. The all solid state support and transducer was build through coating a nickel wire with a composite of graphite powder and an epoxy resin, and next it was coated with a nickel selective PVC membrane, with the optimal composition of 33% of PVC, 57% of Nitrobenzene, 2% RTIL (1-n-butyl-3-methylimidazolium hexafluorophosphate), 3% of KpClTPB, and 5% of ionophore L. The potential response of the ASS-PMS change with the concentration of the target ion at a slope of 29.5 ± 0.3 mV/decade, which is indicative of a Nernstian behavior, and was linear in the concentration range of 1.0 × 10-8 to 1.0 × 10-3 mol L-1 of the nickel(II), reaching a lower detection limit as low as 5.0 × 10-9 mol L-1. The response of the ASS-PMS was found to be almost independent from interference from different conventional ionic species. The ASS-PMS was successfully applied to the potentiometric determination of nickel(II) concentrations in ions electroplating waste water samples. In the experiment, the researchers used many compounds, for example, 2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene (cas: 7128-64-5Computed Properties of C26H26N2O2S).
2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene (cas: 7128-64-5) belongs to benzothiophene derivatives. Benzothiophene is a fused ring compound of thiophene ring and benzene ring, which is an important class of heterocycles with advantageous structures. Due to its aromaticity, thiophenes do not exhibit the same properties as conventional thioethers.Computed Properties of C26H26N2O2S
