活(huo)性炭改性后處理磺胺廢水

　　磺胺廢水(shui)經活性炭改(gai)(gai)(gai)(gai)性后處(chu)理，活性炭經氯化(hua)鐵改(gai)(gai)(gai)(gai)性。并進行批量實驗以評估廢水(shui)中的(de)磺胺二甲嘧啶(ding)吸(xi)附到活性炭和改(gai)(gai)(gai)(gai)性活性炭上(shang)(shang)的(de)平衡，分(fen)別分(fen)析(xi)動力學和熱(re)力學特(te)征。結果表(biao)明，氯化(hua)鐵處(chu)理后，活性炭改(gai)(gai)(gai)(gai)變了(le)(le)表(biao)面(mian)積、孔隙體(ti)積和表(biao)面(mian)zeta電位還增加了(le)(le)表(biao)面(mian)含氧官能團(tuan)的(de)數(shu)量。經試驗發現，磺胺二甲啶(ding)在改(gai)(gai)(gai)(gai)性活性炭上(shang)(shang)的(de)吸(xi)附得到了(le)(le)顯著改(gai)(gai)(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(neng)(neng)有效(xiao)(xiao)去(qu)除(chu)顏(yan)色、氣味、無機(ji)(ji)化(hua)合物和大多數有機(ji)(ji)污(wu)(wu)染物。但(dan)其在實際應用中的(de)(de)使用受其吸(xi)(xi)附(fu)(fu)效(xiao)(xiao)率和成本(ben)低的(de)(de)限制。金屬離子(zi)改(gai)(gai)性(xing)(xing)后的(de)(de)活性(xing)(xing)炭(tan)(tan)生產簡單(dan)便宜，能(neng)(neng)顯著提高活性(xing)(xing)炭(tan)(tan)的(de)(de)吸(xi)(xi)附(fu)(fu)性(xing)(xing)能(neng)(neng)。然而(er)，活性(xing)(xing)炭(tan)(tan)中磺(huang)胺(an)(an)類廢水的(de)(de)吸(xi)(xi)附(fu)(fu)機(ji)(ji)制尚不清楚，對磺(huang)胺(an)(an)類的(de)(de)吸(xi)(xi)附(fu)(fu)能(neng)(neng)力及其理(li)化(hua)性(xing)(xing)質(zhi)知之(zhi)甚少(shao)。本(ben)研究采(cai)用鐵離子(zi)改(gai)(gai)性(xing)(xing)活性(xing)(xing)炭(tan)(tan)。用于探索吸(xi)(xi)附(fu)(fu)機(ji)(ji)制的(de)(de)批量吸(xi)(xi)附(fu)(fu)實驗。磺(huang)胺(an)(an)二甲(jia)啶對活性(xing)(xing)炭(tan)(tan)和改(gai)(gai)性(xing)(xing)活性(xing)(xing)炭(tan)(tan)的(de)(de)吸(xi)(xi)附(fu)(fu)特性(xing)(xing)通(tong)過(guo)吸(xi)(xi)附(fu)(fu)動力學(xue)(xue)、吸(xi)(xi)附(fu)(fu)熱力學(xue)(xue)和吸(xi)(xi)附(fu)(fu)等溫(wen)線進行了研究，為去(qu)除(chu)廢水中的(de)(de)磺(huang)胺(an)(an)污(wu)(wu)染物提供了科學(xue)(xue)依據。
