AB  - Praćena je kinetika adsorpcije aflatoksina B1 i G2 na Ca-klinoptilolitu, u vodenom rastvoru elektrolita, na pH 2 i pH 7 i na temperaturi 37 °C. Dobijeni rezultati pokazuju da proces adsorpcije oba toksina započinje brzom reakcijom i da se najveći deo toksina adsorbuje u prvih nekoliko minuta. Posle ovog brzog procesa sledi znatno sporiji proces u kome se nastavlja vezivanje toksina za aktivne centre mineralnog adsorbenta. Pokazano je metodom početnih brzina da je brzi proces adsorpcije oba toksina reakcija prvog reda, dok je spori proces reakcija nultog reda. Indeksi adsorpcije i brzine adsorpcije zavise od pH sredine. U ispitivanom opsegu koncentracija (500-3000 μg/dm3 postignuti su visoki indeksi adsorpcije kako aflatoksina B1 tako i aflatoksina G2 (> 80%).
AB  - The kinetics of aflatoxins B1 and G2 adsorption on Ca-clinoptilolite at pH 2 and 7, in aqueous electrolyte at 37 °C were studied. For both aflatoxins, the adsorption process begins with a fast reaction whereby most of the toxin is adsorbed in the first few minutes. This fast process is followed by the significantly slower process of aflatoxin bonding at active centers of mineral adsorbent. The initial rate method showed that the fast adsorption process of aflatoxin B1 and G2, at both pH values is a first order reaction, while the slow adsorption process of these aflatoxins is a zero order reaction. The adsorption indexes and adsorption rates for both examined toxins were pH dependent. In the investigated initial toxins concentration ranges (500-3000 μg/dm3), high adsorption indexes were achieved (> 80 %).
