Abstract: 

We proposed a novel and simple RGB-type chromogenic signalling system based on color modulation of Co2+, for safety moisture determination in organic solvents. Cation exchanger KU-2-8 was used as a solid carrier of CoCl2. The color parameter R was shown undergo the greatest change over time, so it was chosen as an analytical signal. The obtained data confirm that changes in color coordinates depend only on the concentration of water in organic solvents, and do not depend on their nature. Grinding of the colored cation exchanger to a powdery state contributed to a significant decrease of the response time of the sensor and an increase of the sensitivity of the sensor by raising the intensity of the analytical signal. This makes it also promising for controlling the humidity of gases. The dependence of R on the water content for a chromophore probe in the form of powdered cationite KU-2-8 impregnated with cobalt (II) chlorides described by the 1st order exponential dependence with the correlation coefficient close to 1.
