中文摘要 | 本研究主要是在探討鈣-蒙特石經三種重金屬離子(鈦、鐵及銅)及兩種染料陽離子(Basic Green 5 (BG5)及Basic Violet 10(BV10))置換後其孔洞結構及對有機氣體吸附特性之變化;其中使用染料陽離子置換主要是為了模擬蒙特石在吸附完廢水中之陽離子型染料後再利用作為吸附劑以去除有機氯體之可能性,換句話說,此部分之研究重點是在於吸附劑之回收及再利用。研究過程首先測量改質蒙特石之氮吸附曲線及XRD繞射圖譜,經由對氮吸附曲線進行傳統及碎形分析及經由XRD圖譜計算得蒙特石矽層間距以探討陽離子置換對蒙特石之表面積、表面碎形維度及孔洞大小及分佈之影響。接著量測在25℃,苯、甲苯及乙苯在上述改質蒙特石上之吸附平衡曲線。最後,我們將對改質過程所造成蒙特石之表面及孔洞結構之變化對蒙特石吸附有機氣體之影響作一探討。 |
英文摘要 | Ca-montmorillonite (Ca-Mont) was exchanged with both metal (titanium, iron, and copper) and organic dye cations (Basic Green 5 (BG5) and Basic Violet 10 (BV 10)) to study the effects of cation exchange on the pore structure and adsorption characteristics of montmorillonite. The BG- montmorillonite (BG5-Mont) and BV10-montmorillonite (BV10-Mont) were used to examine the reusable characteristics of the montmorillonite after it was used to adsorb the dyes from the wastewater solutions. Both the nitrogen isotherms and XRD patterns of the examined montmorillonites were firstly measured. The ion-exchange effects on the surface area, surface fractal dimension, pore size and pore size distribution, and basal spacings [d (001)] of montmorillonites are identified based on the classical and fractal analyses of the nitrogen adsorption isotherms as well as the XRD patterns. The effects of the alteration of both the surface area and pore structure on the adsorption of organic vapors on montmorillonite are discussed. |
