　　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，活性炭能有效(xiao)去(qu)除顏(yan)色、氣味、無機化合物和大多數有機污染物。但其在(zai)實際應用中(zhong)的(de)(de)使(shi)用受其吸(xi)(xi)(xi)附(fu)(fu)效(xiao)率和成(cheng)本(ben)低的(de)(de)限制。金屬離子(zi)改(gai)性(xing)后的(de)(de)活(huo)(huo)性(xing)炭生產(chan)簡單便宜，能顯(xian)著提(ti)(ti)高活(huo)(huo)性(xing)炭的(de)(de)吸(xi)(xi)(xi)附(fu)(fu)性(xing)能。然而，活(huo)(huo)性(xing)炭中(zhong)磺(huang)胺類(lei)廢水的(de)(de)吸(xi)(xi)(xi)附(fu)(fu)機制尚不清楚，對(dui)磺(huang)胺類(lei)的(de)(de)吸(xi)(xi)(xi)附(fu)(fu)能力及(ji)其理化性(xing)質(zhi)知之(zhi)甚少。本(ben)研究采(cai)用鐵離子(zi)改(gai)性(xing)活(huo)(huo)性(xing)炭。用于探索吸(xi)(xi)(xi)附(fu)(fu)機制的(de)(de)批量吸(xi)(xi)(xi)附(fu)(fu)實驗。磺(huang)胺二甲啶對(dui)活(huo)(huo)性(xing)炭和改(gai)性(xing)活(huo)(huo)性(xing)炭的(de)(de)吸(xi)(xi)(xi)附(fu)(fu)特性(xing)通過吸(xi)(xi)(xi)附(fu)(fu)動力學、吸(xi)(xi)(xi)附(fu)(fu)熱力學和吸(xi)(xi)(xi)附(fu)(fu)等溫線進行了(le)研究，為去(qu)除廢水中(zhong)的(de)(de)磺(huang)胺污染物提(ti)(ti)供了(le)科(ke)學依據。

　　1.微孔捕獲

　　SEM圖像(xiang)顯示(shi)，活性炭的(de)規則孔(kong)(kong)結(jie)構(gou)受損，孔(kong)(kong)隙率(lv)增加。TEM圖像(xiang)顯示(shi)，改性活性炭表面(mian)(mian)含有許多透明點，表明孔(kong)(kong)結(jie)構(gou)更發達，修(xiu)改后可獲得(de)更多的(de)吸附(fu)(fu)點。這有利于磺胺二(er)甲啶吸附(fu)(fu)到(dao)黑碳分(fen)子層(ceng)的(de)孔(kong)(kong)中。此外(wai)，經鐵離子改性后，活性炭的(de)表面(mian)(mian)積(ji)(ji)、總孔(kong)(kong)容量、微孔(kong)(kong)體積(ji)(ji)和中孔(kong)(kong)體積(ji)(ji)都有一定程度的(de)增加。
