Preparation, Characterization And Applications Of Multi-Functional Iron Oxides-Impregnated Activated Carbon Materials

Kajian ini telah dijalankan untuk mengkaji penyediaan, pencirian dan aplikasi berbeza karbon teraktif terubahsuai ferum oksida (FeACs). Permukaan karbon teraktif (AC) pada awalnya telah dioksidakan dengan menggunakan kalium permanganat (KMnO4) diikuti impregnasi ferum dengan ferum sulfat (FeSO4.7...

Permukaan karbon teraktif (AC) pada awalnya telah dioksidakan dengan menggunakan kalium permanganat (KMnO4) diikuti impregnasi ferum dengan ferum sulfat (FeSO4.7H2O) sebagai prekursor ferum dengan nisbah molar agen pengoksidaan kepada ferum berbeza untuk mengkaji kesan impregnasi ferum terhadap ciri fizikokimia bahan karbon baru yang disediakan. Pelbagai teknik pencirian seperti analisis luas permukaan, SEM, EDX, TEM, HRTEM, SAED, XRD, FTIR, CHN, TCC, TG/DTA, XPS, VSM, TPR / TPD dan pHpzc telah dijalankan. Permukaan impregnasi AC merubah dengan banyak luas permukaan disamping keliangan bahan yang baharu disediakan. Peningkatan luas permukaan sehingga 1640 m2/g didapati untuk AC yang terubahsuai, dengan nisbah molar 0.1 KMnO4 : 0.1 FeSO4.7H2O (B), adalah lebih tinggi daripada AC mentah (1094 m2/g). This study was conducted to investigate the preparation, characterization and different applications of iron oxides-impregnated activated carbon materials (FeACs). The surface of activated carbon (AC) was initially oxidized by using potassium permanganate (KMnO4) followed by the iron impregnation using ferrous sulphate (FeSO4.7H2O) as iron precursor using different molar ratios of the oxidizing agent to the iron precursor to examine the impact of iron impregnation on the physicochemical characteristics of the newly prepared carbon materials. Various characterization techniques such as surface area, SEM, EDX, TEM, HRTEM, SAED, XRD, FTIR, CHN, TCC, TG/DTA, XPS, VSM, TPR/TPD and pHpzc analyses were carried out. The surface impregnation of AC varies the surface area as well as the porosity of the newly prepared materials to a great extent. It depicted an increase in the surface area up to 1640 m2/g for modified AC having molar ratio 0.1 KMnO4 : 0.1 FeSO4.7H2O (B), which was comparatively higher than the raw AC (1094 m2/g). 2016-03 Thesis http://eprints.usm.my/31588/ http://eprints.usm.my/31588/1/IRFAN_SHAH_24.pdf application/pdf en public phd doctoral Universiti Sains Malaysia Pusat Pengajian Sains Kimia (School of Chemical Sciences)
