中文摘要：

近年来，水环境中抗生素的去除成为关注热点。研究讨论了磺胺嘧啶在颗粒活性炭（GAC）和多壁碳纳米管（MWCNT）上的吸附特性，并考察了pH、离子强度和腐殖酸等因素对吸附的影响。结果表明，pH对吸附效果有着显著的影响；腐殖酸的存在与磺胺嘧啶形成了竞争吸附；离子强度的变化对吸附效果没有很大影响。

英文摘要：

More concerns have been raised on the elimination of antibiotics in the aquatic environment. In the present study, two adsorbents, including granular activated carbon （GAC） and multi-walled carbon nanotube （MWCNT）, were used to adsorb the sulfapyridine （SPY）. The effects ofpH, ionic strength, and humic acid on sulfapyridine adsorption were also assessed. It is suggested that pH has a significant effect on adsorption. The presence of humic acid can cause direct competitive adsorption with sulfapyridine. However, the ionic strength doesn＇t affect much on sulfapyridine adsorption.
