Abstract	Fabric matrices made of viscose and cotton fiber with adsorption-immobilized organic reagents are considered with respect to their possible use for chemical test methods of analysis. Triarylmethane, thiazine, eurhodine, acridine, azo, and diazo compounds are used for immobilization. It is found that the degree of reagent retention (R, %) depends on the pH and the type of the matrix used. R varies within 12–99%. The absorption spectra of the reagents immobilized on fabric matrices exhibit hypsochromic or bathochromic shifts of absorption bands (2–45 nm as compared to their absorption spectra in solution). As a rule, the degree of retention is higher for the reagents that exhibit a shift of the absorption band on the support. The adsorption isotherms of the reagents on various cellulose supports are analyzed. Test procedures are developed for the determination of antimony and mercury using modified fabric matrices. The rapidity, precision, and sensitivity of previously developed procedures for the test determination of Cu(II), Cd, and S$^{2−}$ are improved. The relative standard deviations of the determinations are no more than 0.1; the analysis time is 5–10 min.
