Abstract
The sorption of ion associates of acidic azo dyes, sulfonazo and Congo red, with Dimedrol on polyurethane foams is studied depending on pH, phase contact time, and component ratio. A method for determining Dimedrol in medicinal products is developed based on its sorption as ion associates with dyes and subsequent detection on the sorbent surface by diffuse reflectance spectroscopy.
期刊介绍：
The Journal of Analytical Chemistry is an international peer reviewed journal that covers theoretical and applied aspects of analytical chemistry; it informs the reader about new achievements in analytical methods, instruments and reagents. Ample space is devoted to problems arising in the analysis of vital media such as water and air. Consideration is given to the detection and determination of metal ions, anions, and various organic substances. The journal welcomes manuscripts from all countries in the English or Russian language.
