The trends analysis of chemical chromaticity method evolution (Review)

Abstract

Scientometric analysis of chemical chromaticity method trends was done for the last 20 years. For the next 10 years a steady interest in approaches chemical chromaticity method can be predicted by analysis of the obtained logistic curve. The basic directions of the chemical chromaticity method were marked. They are materials science, food chemistry and analytical chemistry. The chemical chromaticity method advantages over classical physicochemical methods of research were shown in the practice of chemical analysis. For the acid-base equilibrium study and ionization constants determination it is not necessary to operate the concentrations dye's ion-molecule forms in the solution. The potentials of chromaticity functions use for creating sorp-tion-chromaticity and extraction-chromaticity methods of quantitative analysis were noted. Nowadays the semi-quantitative visually colorimetric test method are most intensively created. In recent years, there has been a steady increasing in the chromaticity techniques of quantitative analysis related to the area expansion of chemical chromaticity method use and the nature of the analyzed objects.

The Impregnated Fibrous Chemisorbents for Colorimetric Detection of the Sulfur Dioxide

“…Besides this, digital colorimetry in aqueous solutions and on different surfaces is use in addition to spectrophotometry to solve different chemical and analytical problems [7][8][9][10][11][12]. However, there is no theoretical basis today for the development of indicator chemisorbents of acid gases such as sulfur dioxide.…”
