　　磺胺廢(fei)水經(jing)活(huo)(huo)(huo)(huo)性(xing)(xing)炭(tan)改(gai)(gai)性(xing)(xing)后(hou)處理，活(huo)(huo)(huo)(huo)性(xing)(xing)炭(tan)經(jing)氯化鐵改(gai)(gai)性(xing)(xing)。并進行批量(liang)實驗以(yi)評估廢(fei)水中(zhong)的磺胺二甲嘧啶(ding)吸(xi)附(fu)到活(huo)(huo)(huo)(huo)性(xing)(xing)炭(tan)和(he)改(gai)(gai)性(xing)(xing)活(huo)(huo)(huo)(huo)性(xing)(xing)炭(tan)上(shang)的平衡，分別分析(xi)動力(li)學和(he)熱(re)力(li)學特征。結果表(biao)明，氯化鐵處理后(hou)，活(huo)(huo)(huo)(huo)性(xing)(xing)炭(tan)改(gai)(gai)變了(le)表(biao)面積(ji)(ji)、孔隙(xi)體積(ji)(ji)和(he)表(biao)面zeta電位還增加了(le)表(biao)面含氧(yang)官能團的數量(liang)。經(jing)試驗發(fa)現，磺胺二甲啶(ding)在(zai)改(gai)(gai)性(xing)(xing)活(huo)(huo)(huo)(huo)性(xing)(xing)炭(tan)上(shang)的吸(xi)附(fu)得到了(le)顯著改(gai)(gai)善。

　　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，活性炭能有效去除顏色、氣(qi)味、無機化合物和大多(duo)數有機污染(ran)物。但其(qi)在實際應用中的(de)(de)(de)使(shi)用受其(qi)吸(xi)(xi)附(fu)(fu)(fu)效率和成本低(di)的(de)(de)(de)限制。金屬離子改性(xing)后的(de)(de)(de)活(huo)(huo)性(xing)炭(tan)生產簡單便宜(yi)，能顯著提高(gao)活(huo)(huo)性(xing)炭(tan)的(de)(de)(de)吸(xi)(xi)附(fu)(fu)(fu)性(xing)能。然而，活(huo)(huo)性(xing)炭(tan)中磺(huang)(huang)胺類(lei)(lei)廢(fei)水(shui)的(de)(de)(de)吸(xi)(xi)附(fu)(fu)(fu)機制尚(shang)不清楚，對磺(huang)(huang)胺類(lei)(lei)的(de)(de)(de)吸(xi)(xi)附(fu)(fu)(fu)能力(li)及(ji)其(qi)理化性(xing)質知之(zhi)甚少。本研(yan)究采用鐵離子改性(xing)活(huo)(huo)性(xing)炭(tan)。用于探索吸(xi)(xi)附(fu)(fu)(fu)機制的(de)(de)(de)批量吸(xi)(xi)附(fu)(fu)(fu)實驗。磺(huang)(huang)胺二甲(jia)啶對活(huo)(huo)性(xing)炭(tan)和改性(xing)活(huo)(huo)性(xing)炭(tan)的(de)(de)(de)吸(xi)(xi)附(fu)(fu)(fu)特性(xing)通過吸(xi)(xi)附(fu)(fu)(fu)動力(li)學(xue)、吸(xi)(xi)附(fu)(fu)(fu)熱力(li)學(xue)和吸(xi)(xi)附(fu)(fu)(fu)等溫(wen)線進行了(le)研(yan)究，為去除廢(fei)水(shui)中的(de)(de)(de)磺(huang)(huang)胺污染(ran)物提供了(le)科學(xue)依據。
