Abstract
IR spectroscopic method for determination of zeolite deposited on textiles after washing with zeolite containing detergents has been developed. The total inorganic deposits on the textiles were determined as percentual contents of textile ashes according to DIN 44983. Zeolite contents in the ash were determined by IR method, using as a standard additive zeolite thermally treated at 1073K for 2h. Calibration diagram was obtained by measuring band intensity at v=680 cm−1 of the standard in ash samples with known standard contents. Comparative analysis has shown good agreement between the results obtained by the proposed method and chemical analysis of ashes. Repeated determination of zeolite contents in the same sample has shown good reproducibility and reliability of the method.
