“…One type of ISEs, sensors based on PVC have been used for the determination of drug 22 , cations [23][24][25][26][27][28][29][30][31][32][33][34][35] and anions [36][37] with different ligands like crown ether [38][39][40][41][42] , porphyrin 37,[43][44][45] according to Gupta et al Carbon paste electrodes (CPEs) are another type of ISEs that are used as working electrodes in electrochemical methods in recent decades [46][47][48][49][50][51][52][53][54][55] . CPEs are prepared from graphite powder and organic liquid like paraffin.…”

“…It has been shown that single metallic oxides could not fulfill the criterion to compose the perfect gas sensing matrix. Therefore, to overcome this imperfection, the sensing capability of monometallic oxides has been improved with the additives of other metal oxide such as ZnO, CuO, WO 3 , In 2 O 3 or SnO 2 to form the complex multicomponent materials [32][33][34][35][36][37][38][39]. These additives enhance the sensor sensitivity and improve their selectivity for a particular gas, decrease the response and recovery times, stabilize a particular valence state, favor formation of active phases or increase the electron acceptor rate.…”

“…Nevertheless, there is still a discussion about the way of SnO 2 doping into titania, which affects the gas sensing mechanism. From the general point of view, SnO 2 doping is thought to modify the microstructure of the base material, to control grain growth mechanism and to introduce electronic states at the surface or into the bulk of the grain giving a change to the modification of the base material conductivity and of the gas sensing properties [38][39][40][41].…”

Present paper reports the synthesis of nanostructured (Sn-Ti)O 2 via physicochemical method, its characterization and performance as liquefied petroleum gas (LPG) sensor. The synthesized material was characterized using XRD that confirmed the formation of (SnTi)O 2 nanocomposite. Minimum crystallite size was found as 7 nm. The material was also investigated through SEM, DSC, FTIR, PL and UV-Vis spectrophotometer. Further, the pellet, thick and thin films were fabricated for the sensing analysis. Pellets (9 mm diameter, 4 mm thickness) of (Sn-Ti)O 2 nanocomposite were made by hydraulic pressing machine by applying uniaxial pressure of 616 MPa, thick films (thickness *2 lm) were made by screen printing technique and thin films were prepared using a Photo resist spinner unit. Further at room temperature, the pellet and films were exposed to LPG in a gas chamber under controlled conditions at room temperature and variations in resistance with the concentrations of LPG were observed. The maximum value of sensitivity of solid state pellet, thick and thin films based sensors were found 7, 9 and 39 for 5 vol% of LPG, respectively. Sensing characteristics were found to be reproducible, after 6 months of their fabrication, indicating the stability of the sensors.

The present work focuses on the fabrication of a potentiometric sensor for the determination of zinc ions using 3,7,12,17-Tetramethyl-8,13-divinyl-2,18-porphinedipropionic acid disodium salt (protoporphyrin IX disodium) as the ionophore. The electrode is fabricated by various composition of protoporphyrin IX disodium, graphite, multiwalled carbon nanotube, paraffin oil, and sodium tetraphenyl borate. These factors are varied at 5 levels. The composition of the electrode is optimized using artificial neural network. The optimization of electrode composition was carried out using genetic algorithm, rotation inherit optimization and particle swarm optimization techniques. The genetic algorithm (GA) optimized electrode was prepared with the composition ionophore (9.71 mg), paraffin oil (drop) (7.17), NaTPB (5.31 mg), graphite (244.82 mg) and MWCNT (21.82 mg) showed better response with a a Nernstian slope of 29.69 mV/decade. It also showed a linear response in the concentration range of 1.0×10 −1 M to 3.09×10 −7 M and a detection limit of 1.9×10 −7 M. The electrode showed a good selectivity for Zn 2+ relative to many studied cations. The GA optimized electrodes showed a stable response in the pH range of 2.7 to 7.0w with a response time less than 20 s for all the tested concentration ranges. Analytical application of the electrode was demonstrated by using the prepared electrode as an indicator electrode for the potentiometric titration of Zn 2+ against EDTA.
