In this work, a novel Zr02+ PVC-based membrane sensor based on 4,7,13,16,21,24-hexa oxa-1,10- diazabicyclo[8,8,8]- hexa cosane (HODBHC) as a new ionophore is presented. The sensor displays a linear dynamic rangebetween 1.0x 10-1 and 1.0x10 6 M, with a near Nernstian slope of 29.9 ± 0.4 mV per decade in an acidic solution(pH=1). The limit of detection is 8.0 x 1 0 7 M. The electrodes possess adv...

A new polyvinyl choloride (PVC) membrane sensor for cerium (III) was prepared based on 4,13-didecyl-1,7,10,16-tetraoxa-4,13-diazacyclooctadecane (kryptofix22DD) as an ionophore. The sensor exhibites a linear concentration range of 1.0×10-6 to 1.0×10-1 M, with a Nernstian slope of 18.0±1.0 mV/decade, and a detection limit of 9.7×10-7 M. It has a fast response time (5 s) and can be used for two m...

Design and application of powder composite electrodes for electrosynthesis and electroanalysis research has been carried out. The physical characterization of electrodes was analysis using SEM, EDX and FTIR. The electrochemical stability was analysis using cyclic voltammetry. The stability of electrodes was analyzed using Atomic Absorption Spectroscopy (AAS). The powder composite electrodes wer...

In this research, a carbothioamide derivative molecule was synthesized to be used as an electroactive material, and poly (vinyl chloride) (PVC) membrane lead(II)–selective potentiometric sensors with different components were prepared. Among various compositions, the best performance exhibited by having bis(2–ethylhexyl)sebacate (BEHS), PVC, potassium tetrakis(p–chlorophenyl)borate (KTpClPB) in...

A novel PVC membrane sensor for the Sr ion based on 1,10-diaza-5,6-benzo-4,7dioxacyclohexadecane-2,9-dione has been prepared. The sensor possesses a Nernstian slope of 30.0 ± 0.6 mV decade over a wide linear concentration range of 1.6 × 10-3.0 ×10 M with a detection limit of 6.3 ×10 M. It has a fast response time of <15 s and can be used for at least two months without any considerable divergen...

This work describes the use of an array of potentiometric sensors and an artificial neural network response model to determine perchlorate and sulfide ions in polluted waters, by what is known as an electronic tongue. Sensors used have been all-solid-state PVC membrane selective electrodes, where their ionophores were different metal-phtalocyanine complexes with specific and anion generic respo...
