a new al(iii) selective membrane based on 5-bromo(salicylidene-2-amino thiophenol) as a neutral carrier in a poly(vinyl chloride) (pvc) matrix is coated on platinum wire to determine trace amounts of al(iii) ion in various samples. the sensor exhibits a good response for al(iii) ion over a wide concentration range of 5.20 × 10-7 to 1.00 × 10-2 m  with nernstian slope of 19.64 ± 0.15 mv decade-1...

a poly(vinyl chloride) membrane based on a new a-dioxime derivative as membrane carrier was prepared andinvestigated as a cr(iii) selective electrode. the electrode exhibits a good potentiometric response for cr(iii)over a wide concentration range 1.0 x 10-6 to 1.0 x 10-1 m with a slope 19.5+0.5 mv/decade and low detectionlimit of 8.9 x 10-7 m. it has a fast response time < 15 s. the best perfo...

A selective optical sensor based on immobilization of Eriochrome Cyanine R for the determination of Al(III) ions in aqueous solution has been developed. The method is based on the spectrophotometric measurement of complex Eriochrome Cyanine R-aluminium at 537 nm. The sensing membrane is made of a triacetylcellulose film containing Eriochrome Cyanine R colorimetric reagent immobilized as an ion ...

This study presents a sensor neural network inspired by mouse taste buds for input signal identification. The sensor neural network model consisted of two layers of spiking cells: 4 Type II and 2 Type III cells. The Type II cells were receptive cells, and the Type III cells were output cells. The sensor network model converted differences in the sensory input into the degree of synchronization ...

the preparation of vegetation cover maps by used the land inventory and a traditional method has a lot of cost and time. but today, remote sensing is one of the main sources of data collection and information production for study and monitoring land resources, and was efficient tools for providing quickly and timely data and information needs for program planning in the natural resource filed. ...

N,N’-bis(2piridinacarboxamida)-1,2-benzeno (H 2 BPB) apresentou um comportamento seletivo e sensível, frente ao íon Ho(III), em comparação a um grande número de íons de metais de transição interna, representativos e de lantanídeos, tendo sido portanto, aplicado como um ionóforo neutro para preparação de uma membrana sensora Ho(III), com alta seletividade e sensitividade. As membranas também con...
