Abstract

Настоящее изобретение раскрывает способ селективного определения. Отличительной особенностью данного способа является применение люминесцентной мультизондовой системы, у которой в присутствии различных ионов спектр флуоресценции меняется различным образом. Изменения интенсивности флуоресценции различных зондов, входящих в мультизондовую систему, на длинах волн, соответствующих максимумам спектра, формируют векторный сигнал мультизондовой системы. После калибровки этого векторного сигнала к воздействию требуемых ионов тяжелых металлов его обрабатывают методами распознавания образов и после обработки записывают в калибровочную базу данных. Анализ ионного состава неизвестного тестового раствора проводят по той же процедуре, что и запись калибровочных данных. Полученные тестовые сигналы сравнивают с калибровочными и принимают решение о виде ионов, входящих в неизвестный тестовый раствор, и их концентрации. Технический результат заявляемого изобретения заключается в возможности эффективного распознавания в растворе вида ионов тяжелых металлов.The present invention discloses a method for selective determination. A distinctive feature of this method is the use of a luminescent multi-probe system, in which, in the presence of various ions, the fluorescence spectrum changes in various ways. Changes in the fluorescence intensity of various probes included in the multi-probe system at wavelengths corresponding to the maxima of the spectrum form a vector signal of the multi-probe system. After calibrating this vector signal to the effects of the required heavy metal ions, it is processed by pattern recognition methods and, after processing, recorded in a calibration database. Analysis of the ionic composition of an unknown test solution is carried out according to the same procedure as the recording of calibration data. The received test signals are compared with the calibration ones and decide on the type of ions entering the unknown test solution and their concentration. The technical result of the claimed invention lies in the possibility of effective recognition in solution of the type of heavy metal ions.
