磺胺类抗生素是水体的持久性污染物，已知会诱导高水平的细菌耐药性。我们研究了磺胺嘧啶，磺胺二甲嘧啶，磺胺氯哒嗪磺胺到一个高度脱铝八面沸石（Y）的笼形窗口大小可比的磺胺尺寸的吸附。在最大溶解度下，抗生素几乎完全（>90%）和快速（> 90%）溶解。
Sulfonamide antibiotics are persistent pollutants of aquatic bodies, known to induce high levels of bacterial resistance. We investigated the adsorption of sulfadiazine, sulfamethazine, and sulfachloropyridazine sulfonamides into a highly dealuminated faujasite zeolite (Y) with cage window sizes comparable to sulfonamide dimensions. At maximal solubility the antibiotics were almost completely (>90%) and quickly (t
