%X active zeolite products (azp) are enriched with a cathion that determines their animicrobial effects. the extraction conditions were set taking inherent features of the raw material and its forms - tablets and creams - into account. different treatment were applied to samples under optimized working conditions. zinc conten was estimated by x - ray fluorescence and atomic absorption spectrophotometry. there - acid effect treatment with h2do4 hno (2:3) and hcl as an optimal method for treatting tablets and creams was shown whereas the active principla (az) was treated with ion - exchange.
