[Adsorption effects of mineral adsorbent on the clinoptilolite basis, part 2: Adsorption behaviour in the presence of aminoacids and vitamins]. [English]

The results present in this paper were obtained by studying the adsorption effects of a mineral adsorbent on clinoptilolite, in contact with some aminoacids (tryptophan and phenylalanine) and vitamins (A,D and E). The chemisorption index was developed as a measure of adsorption intensity. The chemisorption index showed the ratio between adsorbed and total ligand concentration. The results obtained with aminoacids and vitamins were compared with previous results obtained with aflatoxins (B1,B2 and G2), zearalenone, ochratoxin and T2 toxin under identical conditions. It was found that neither aminoacids nor vitamins were adsorbed by this mineral adsorbent. The chemisorption index was different for different toxins.
