Abstract:: ... This study described the adsorption of chloramphenicol (CAP) in wastewater on the renewable bioresource of bamboo charcoal (BC). Results showed that CAP adsorption on BC (Ln qe =1.272 Ln Ce +1.971) and H₂SO₄ modified BC (Ln qe =1.851 Ln Ce +0.659) were very slight, and on NaOH modified BC was significantly increased (Ln qe =0.344 Ln Ce +6.490). The adsorbents were characterized by N₂ adsorption-de ...

Abstract:: ... Four typical kinds of crop seeds are studied as non-metallic bio-precursors to synthesize biogenic N-P-codoped TiO₂ (BNP-TiO₂). The as-prepared BNP-TiO₂ samples are characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), nitrogen-adsorption measurement and UV-Vis spectroscopy. The results show that BNP-TiO₂ possesses single anatase phase with mesopore structures, and nitr ...

Abstract:: ... The immobilization of lipase B from Candida antarctica on smectite group nanoclays (Laponite, SWy-2 and Kunipia), as well as on their organically modified derivatives, was investigated. A combination of techniques, namely X-ray diffraction, thermal analysis, X-ray photoelectron and FT-IR spectroscopy, was used for characterization of the novel immobilized biocatalyst. Structural and biochemical ch ...

Abstract:: ... Selenium oxyanions are toxic to living organisms at excessive levels. The accumulation of selenium in certain environments requires the development of efficient detoxification processes. In this study, we demonstrated the ability of two Anaeromyxobacter dehalogenans strains to readily convert toxic Se(IV) to less toxic insoluble Se(0), as confirmed by energy-dispersive X-ray spectrometry and X-ray ...

Abstract:: ... A novel organic-inorganic hybrid membrane as heterogeneous acid catalyst for biodiesel production was prepared from zirconium sulfate (Zr(SO₄)₂) and sulfonated poly(vinyl alcohol) (SPVA). The structure and properties of the hybrid catalytic membrane were investigated by means of Fourier transform infrared spectroscopy (FTIR), differential scanning calorimeter (DSC), thermogravimetry (TG), transmis ...

Abstract:: ... Spent grain (SG) was functionalized with thioglycollic acid in N,N-dimethylformamide (DMF) medium using sodium bisulfate monohydrate (NaHSO₄·H₂O) as a catalyst, followed by treatment with sodium sulfide nonahydrate (Na₂S·9H₂O). Characterization of thiol-functionalized spent grain (TFSG) was performed using X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FTIR) spectroscopy. T ...
