“…Developing the information system with incorporated elements for chemo-sensitivity is necessary, in the first order, to solve the problem of sensitive detectors of high quality as well as problem of the data input in general. Some prototypes of such ISs had been already presented in some our works as well as the works of other authors [1] - [4], [6] - [11], [16]. One of such automated information system (AIS) had been described in [1] - [4].…”

“…Other, the second group of detectors included detectors with surfaces, covered with thin layers, films or membrane with ion-selective properties. They can be done in artificial manner, like ion-selective glasses of electrodes [14] - [16], and we studied theoretical possibility to incorporate them into developed IS [7], [10], [11], [17], [18]. The first works with such glasses were done previously by B. P. Nikol'sky and then by A.…”

“…A. Lev [19], [20]. Such specific sensory elements (chemosensitive membranes (artificial and/or natural origin), specific coverings and layers of substances) after the contact with certain environmental chemicals are able to form the signals about pollutants presence and, in some cases, to perform their initial identification [14] - [16]. The latter is the most desirable for the development of multi-functional portable sensors.…”

“…The latter is the most desirable for the development of multi-functional portable sensors. Studies aimed on the construction of devices for the detecting various environmental pollutants were based on a detailed study of membrane systems that simulate the main physicochemical properties of artificial and natural membranes, including their selectivity to ions; and such studies were becoming increasingly important [14] - [16]. This is especially necessary during a fire extinguishing and eliminating of other consequences of accidents, catastrophes at large industrial enterprises and objects of energetic, when extinguishing algorithms have to be linked quickly with current state of the object.…”

“…Detecting subsystem for such devices can include sensory elements, like chemo-sensitive membranes (of natural origin and/or artificial ones), layers from specific substances, coatings, and etc. [10], [16]. Such elements being in contact with some acted chemicals have to reveal chemo-sensitivity and; in some cases, even ability for primary processing of information, doing initial identification of these substances [10], [11].…”

Ecological monitoring is a real need in contemporary world with its growing tendency of environmental industrial pollution. Among such pollutants there are chemicals emanated in fires, explosions and other emergencies, in process of ruining of chemical enterprises, enterprises of oil and gas cycle, and etc. Some information systems for appropriate monitoring were described briefly in this article together with incorporated hybrid system of electronic chemical pollution detectors that were able to input information to such systems. In previous works of the authors the necessity of development of two types of such detectors with specified properties were substantiated: biosensors and detectors with elements – artificially elaborated selective membranes. This article describes the second type of detectors. The proposed detectors were able to detect harmful chemicals in the environment in the air and water phases; development of such devices was based on the theory of membrane systems. The detectors contained sensor elements covered with chemo-sensitive specific coatings – layers of substances: membranes, films, etc. When in contact with certain chemicals, these detectors demonstrate the properties of chemo-sensitivity and primary identification of such compounds. These studies were aimed on developing detectors of various environmental pollutants based on the theory that can be used as a basis for the detection of such substances. The works were based on a deep study of membrane systems with further development of physical and mathematical models of some substances detection taking into account basic chemical and physical properties of artificial and natural membranes, as well as their ionic selectivity. Some results of mathematical modeling of such detectors with artificial membranes – chemo-sensitive surfaces – were described in the article. Summarizing the previous experience, a brief review of authors’ publications in these items was done, as well as the works of some other authors. The purpose of the work was, basing on profound studying of artificial membrane systems, to suggest them as physical model and summarize the experience of development of their mathematical models.
