　　磺胺二甲啶是一種新型污染物，主要用于治療各種細菌感染引起的疾病。大多數磺胺二甲嘧啶以磺胺或代謝物的形式通過動物糞便和尿液釋放到環境中。這些磺胺或代謝物可能長期存在于環境中，可通過農場徑流和城市污水處理廠進入土壤、地表水、地下水甚至飲用水。傳統的污水處理技術只能去除廢水中的一些抗生素。這促使研究人員開發簡單高效的新技術，有效處理磺胺廢水。由于比表面積大，孔結構復雜，活性炭能(neng)(neng)有效(xiao)去(qu)除顏色、氣(qi)味(wei)、無機(ji)化(hua)合物(wu)(wu)和(he)大(da)多數有機(ji)污染物(wu)(wu)。但其在(zai)實(shi)際應用中的(de)(de)(de)使用受其吸(xi)(xi)附(fu)效(xiao)率和(he)成本(ben)低的(de)(de)(de)限制(zhi)。金(jin)屬離(li)子改(gai)性(xing)(xing)后(hou)的(de)(de)(de)活(huo)性(xing)(xing)炭(tan)生(sheng)產簡(jian)單便(bian)宜(yi)，能(neng)(neng)顯(xian)著提(ti)高活(huo)性(xing)(xing)炭(tan)的(de)(de)(de)吸(xi)(xi)附(fu)性(xing)(xing)能(neng)(neng)。然(ran)而，活(huo)性(xing)(xing)炭(tan)中磺胺類(lei)(lei)廢水(shui)的(de)(de)(de)吸(xi)(xi)附(fu)機(ji)制(zhi)尚不清楚，對磺胺類(lei)(lei)的(de)(de)(de)吸(xi)(xi)附(fu)能(neng)(neng)力及其理化(hua)性(xing)(xing)質(zhi)知(zhi)之(zhi)甚少。本(ben)研究(jiu)采用鐵離(li)子改(gai)性(xing)(xing)活(huo)性(xing)(xing)炭(tan)。用于探索吸(xi)(xi)附(fu)機(ji)制(zhi)的(de)(de)(de)批(pi)量吸(xi)(xi)附(fu)實(shi)驗。磺胺二(er)甲(jia)啶(ding)對活(huo)性(xing)(xing)炭(tan)和(he)改(gai)性(xing)(xing)活(huo)性(xing)(xing)炭(tan)的(de)(de)(de)吸(xi)(xi)附(fu)特性(xing)(xing)通過吸(xi)(xi)附(fu)動力學、吸(xi)(xi)附(fu)熱力學和(he)吸(xi)(xi)附(fu)等溫線(xian)進行了研究(jiu)，為去(qu)除廢水(shui)中的(de)(de)(de)磺胺污染物(wu)(wu)提(ti)供了科學依據(ju)。
