摘要: 本研究嘗試披覆黃鐵礦(Pyrite, FeS2)於粒狀活性碳(Granular activated carbon, GAC)上製備一具反應性之吸附劑(GAC-FeS2),以用於處理受三氯乙烯(Trichloroethylene, TCE)氯化有機物污染之水體。GAC-FeS2之製備程序為:(i)以濕式浸潤法將Fe3+沉浸至GAC孔隙結構內;(ii)於300oC煅燒下將Fe3+轉化為氧化鐵(Fe2O3)及(iii)於400oC下以硫粉使Fe2O3硫化為FeS2,分析結果顯示,經由硝酸氧化前處理GAC所製備之複合材料具17%(by wt) FeS2,BET表面積為273 m2/g及孔隙體積為0.168 cm3/g。對於應用於處理TCE之程序可分為兩階段:(i)GAC吸附及FeS2還原脫氯—藉由吸附移除液相TCE(80 mg/L),吸附約於15 h內達平衡,TCE於GAC-FeS2上並同時藉由FeS2降解TCE,反應結果得知720 h後約有10% TCE經由FeS2還原脫氯釋出Cl-;(ii)過硫酸鹽(Persulfate, S2O82-, PS)氧化再生TCE吸附飽和之GAC-FeS2—藉由FeS2活化PS以產生硫酸根自由基以破壞吸附相之TCE,經五次循環再生吸附飽和之GAC-FeS2過程中,於再吸附TCE之循環中,得知GAC-FeS2之再吸附量約可維持80%之初始吸附量,而第一次再生過程中反應24 h後有60%吸附於GAC-FeS2上之TCE被氧化而釋出Cl-,且經由Thiele-modulus模式分析結果亦證實,PS可於GAC孔隙中有效傳輸,以達破壞降解TCE之目的及再生GAC-FeS2之反應性。
The objective of this study was to synthesize reactive adsorbent, i.e., pyrite (FeS2) coated granular activated carbon (GAC) for the purpose of groundwater remediation of trichloroethylene (TCE). The synthesis processes of the composites followed the steps: (i) embedding of GAC with Fe3+ via incipient wetness impregnation method, (ii) iron transformed into iron oxide (Fe2O3) under calcinations of GAC/Fe3+ at 300oC, and (iii) thereafter, further calcinations of Fe2O3 at 400oC in the presence of sulfur powders to form FeS2. The results of analysis showed that the GAC-FeS2 composite made from HNO3 pretreated GAC exhibited 17% (by wt) contents of FeS2, surface area of 273 m2/g and pore volume of 0.168 cm3/g. Furthermore, GAC-FeS2 can be applied for subsurface remediation via two routes: (i) Adsorption of TCE onto GAC-FeS2 and simultaneous dechlorination of TCE by FeS2 - The results showed that removal of TCE from aqueous phase was equilibrated at around 15 h and 10% of sorbed TCE was degraded to release chloride after 720 h; (ii) Regeneration of GAC-FeS2 by persulfate (S2O82-) - Spent GAC-FeS2 was regenerated with sulfate radicals formed by FeS2 activated persulfate. The results showed that after five regeneration cycles sorption capacity was still around 80% of its original capacity. During the 1st regeneration cycle, the concentration of chloride ions liberated after 24 h of regeneration reaction was equivalent to around 60% of sorbed TCE being destroyed. Moreover, the results of analysis with Thiele-modulus model indicated that PS can be effectively diffuse from the bulk solution into GAC-FeS2 pores and to potentially destroy TCE for achieving the ultimate goal of long-term use of GAC-FeS2.
