Abstract

The permissible environmental limit values were studied, and an optimal organic reagent was selected. A sorption spectroscopic method for the determination of chromium (III) ions in industrial wastewater was developed. A suitable sorbent for the selected organic reagent was chosen. The immobilization methodology was developed and implemented. Immobilization was carried out using the selected carrier. The pH dependence of the formation of the complex between the organic reagent and chromium (III) ion was studied. The structure of the complex formed by the immobilized nitroso-R-salt reagent and the mechanism of reagent immobilization onto the fiber were confirmed using Scanning Electron Microscope (SEM) and X-ray fluorescence.
