　　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(hua)合物(wu)和(he)(he)大(da)多數有機污(wu)(wu)染(ran)物(wu)。但其在實(shi)際應用中(zhong)的(de)使用受(shou)其吸(xi)(xi)(xi)附(fu)效(xiao)率和(he)(he)成本低的(de)限制。金屬離子改性(xing)(xing)(xing)(xing)后的(de)活(huo)(huo)性(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)生(sheng)產(chan)簡單(dan)便宜，能顯著提高(gao)活(huo)(huo)性(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)的(de)吸(xi)(xi)(xi)附(fu)性(xing)(xing)(xing)(xing)能。然而，活(huo)(huo)性(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)中(zhong)磺胺類廢水的(de)吸(xi)(xi)(xi)附(fu)機制尚(shang)不清楚，對磺胺類的(de)吸(xi)(xi)(xi)附(fu)能力及其理化(hua)性(xing)(xing)(xing)(xing)質知(zhi)之甚少。本研究(jiu)采用鐵離子改性(xing)(xing)(xing)(xing)活(huo)(huo)性(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)。用于探(tan)索吸(xi)(xi)(xi)附(fu)機制的(de)批量吸(xi)(xi)(xi)附(fu)實(shi)驗。磺胺二(er)甲啶對活(huo)(huo)性(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)和(he)(he)改性(xing)(xing)(xing)(xing)活(huo)(huo)性(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)的(de)吸(xi)(xi)(xi)附(fu)特(te)性(xing)(xing)(xing)(xing)通過(guo)吸(xi)(xi)(xi)附(fu)動力學、吸(xi)(xi)(xi)附(fu)熱力學和(he)(he)吸(xi)(xi)(xi)附(fu)等溫線(xian)進行了研究(jiu)，為(wei)去(qu)除廢水中(zhong)的(de)磺胺污(wu)(wu)染(ran)物(wu)提供(gong)了科學依(yi)據。

　　活性炭吸附磺胺的三個階段(duan)

　　活性(xing)炭(tan)(tan)(tan)和(he)(he)改(gai)性(xing)活性(xing)炭(tan)(tan)(tan)和(he)(he)改(gai)性(xing)活性(xing)炭(tan)(tan)(tan)上(shang)的(de)(de)(de)(de)吸(xi)(xi)(xi)附(fu)(fu)和(he)(he)擴(kuo)散(san)(san)(san)過(guo)(guo)程可分三個階段描(miao)述(shu)，如(ru)圖2所(suo)示(shi)。由(you)于(yu)**階段吸(xi)(xi)(xi)附(fu)(fu)在活性(xing)炭(tan)(tan)(tan)表(biao)面(mian)，吸(xi)(xi)(xi)附(fu)(fu)率*初很高。然后，在顆粒內快速擴(kuo)散(san)(san)(san)的(de)(de)(de)(de)過(guo)(guo)程中，磺胺(an)二(er)甲(jia)啶逐漸(jian)吸(xi)(xi)(xi)附(fu)(fu)在活性(xing)炭(tan)(tan)(tan)上(shang)，吸(xi)(xi)(xi)附(fu)(fu)率常數逐漸(jian)降低。在第三階段，邊界層(ceng)和(he)(he)傳質阻力的(de)(de)(de)(de)影響增加，導致顆粒擴(kuo)散(san)(san)(san)減慢(man)。所(suo)有三個階段的(de)(de)(de)(de)擬合方程都沒有通過(guo)(guo)坐標的(de)(de)(de)(de)原點(dian)，這表(biao)明顆粒的(de)(de)(de)(de)擴(kuo)散(san)(san)(san)并(bing)不是控制(zhi)吸(xi)(xi)(xi)附(fu)(fu)率的(de)(de)(de)(de)**步驟。因(yin)此，吸(xi)(xi)(xi)附(fu)(fu)過(guo)(guo)程也受膜擴(kuo)散(san)(san)(san)和(he)(he)表(biao)面(mian)吸(xi)(xi)(xi)附(fu)(fu)的(de)(de)(de)(de)影響。

　　1.微孔捕獲

　　SEM圖像(xiang)顯示(shi)，活性(xing)炭(tan)的規(gui)則孔(kong)結構受(shou)損，孔(kong)隙率增加(jia)。TEM圖像(xiang)顯示(shi)，改(gai)(gai)性(xing)活性(xing)炭(tan)表面含有許多透(tou)明點(dian)，表明孔(kong)結構更(geng)發達(da)，修改(gai)(gai)后可獲得(de)更(geng)多的吸附點(dian)。這有利于磺胺二甲啶吸附到(dao)黑碳分子層的孔(kong)中(zhong)。此(ci)外，經鐵離子改(gai)(gai)性(xing)后，活性(xing)炭(tan)的表面積、總孔(kong)容量、微孔(kong)體積和(he)中(zhong)孔(kong)體積都有一定程度的增加(jia)。

　　2.氫鍵相(xiang)互(hu)作用(yong)

　　通過FTIR通過促進改性活(huo)性炭表面(mian)與(yu)磺胺(an)二甲(jia)啶之間(jian)氫鍵(jian)的相互作用，促進磺胺(an)二甲(jia)啶的吸附(fu)。從數據圖中(zhong)發(fa)現(xian)，3400和2850cm-1處(chu)寬(kuan)吸收峰表明改性活(huo)性炭表面(mian)存在-OH。這些分子間(jian)氫鍵(jian)增(zeng)強了磺胺(an)二甲(jia)啶與(yu)活(huo)性炭的表面(mian)相互作用，預計(ji)將有助(zhu)于活(huo)性炭與(yu)異(yi)磺胺(an)二甲(jia)啶之間(jian)的親和力吸附(fu)。
