活性炭(tan)改性后處理磺胺廢水

　　磺胺(an)廢水(shui)經(jing)活性(xing)炭(tan)改性(xing)后處理，活性(xing)炭(tan)經(jing)氯化(hua)鐵改性(xing)。并進行(xing)批量實(shi)驗以評(ping)估(gu)廢水(shui)中的(de)磺胺(an)二(er)甲嘧啶(ding)(ding)吸附(fu)(fu)到活性(xing)炭(tan)和(he)改性(xing)活性(xing)炭(tan)上(shang)的(de)平衡，分別(bie)分析動力學和(he)熱力學特(te)征。結果表明(ming)，氯化(hua)鐵處理后，活性(xing)炭(tan)改變了(le)表面(mian)(mian)積、孔隙體積和(he)表面(mian)(mian)zeta電位還增(zeng)加(jia)了(le)表面(mian)(mian)含氧官能團的(de)數量。經(jing)試驗發(fa)現，磺胺(an)二(er)甲啶(ding)(ding)在改性(xing)活性(xing)炭(tan)上(shang)的(de)吸附(fu)(fu)得到了(le)顯著改善。

　　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(xiao)去除(chu)顏(yan)色、氣(qi)味、無機(ji)(ji)化合(he)物(wu)和(he)大(da)多數有機(ji)(ji)污(wu)染(ran)物(wu)。但(dan)其(qi)在實際應用(yong)(yong)中(zhong)的(de)使(shi)用(yong)(yong)受其(qi)吸(xi)(xi)附效(xiao)率和(he)成本低的(de)限制。金屬(shu)離子改(gai)性(xing)后的(de)活性(xing)炭(tan)(tan)(tan)生產簡單便宜，能顯著提(ti)(ti)高活性(xing)炭(tan)(tan)(tan)的(de)吸(xi)(xi)附性(xing)能。然而，活性(xing)炭(tan)(tan)(tan)中(zhong)磺(huang)胺(an)類(lei)廢水(shui)的(de)吸(xi)(xi)附機(ji)(ji)制尚不清楚，對磺(huang)胺(an)類(lei)的(de)吸(xi)(xi)附能力及其(qi)理(li)化性(xing)質知之甚少。本研究(jiu)采(cai)用(yong)(yong)鐵離子改(gai)性(xing)活性(xing)炭(tan)(tan)(tan)。用(yong)(yong)于探(tan)索(suo)吸(xi)(xi)附機(ji)(ji)制的(de)批量(liang)吸(xi)(xi)附實驗(yan)。磺(huang)胺(an)二甲啶對活性(xing)炭(tan)(tan)(tan)和(he)改(gai)性(xing)活性(xing)炭(tan)(tan)(tan)的(de)吸(xi)(xi)附特性(xing)通過吸(xi)(xi)附動力學(xue)、吸(xi)(xi)附熱力學(xue)和(he)吸(xi)(xi)附等溫線進行了研究(jiu)，為去除(chu)廢水(shui)中(zhong)的(de)磺(huang)胺(an)污(wu)染(ran)物(wu)提(ti)(ti)供了科學(xue)依(yi)據(ju)。
