Fourier transform infrared spectroscopy; X-radiation; X-ray photoelectron spectroscopy; adsorbents; adsorption; biochar; cation exchange; cations; leaves; pineapples; sorption isotherms; technology; wastewater
Abstract:
... Although tremendous works have been done on metal adsorption via biochar, mechanisms responsible for metal adsorption remain uncertain. This is the first work that provides direct evidence on the identification of Ni(II), Zn(II), and Cu(II) adsorption mechanisms on pineapple leaf biochar (PLB) using surface characteristics analyses, including X-ray photoelectron spectroscope (XPS), Fourier transfo ...

Fourier transform infrared spectroscopy; X-ray photoelectron spectroscopy; adsorption; anions; aqueous solutions; arsenic; biochar; biosorbents; cadmium; cations; energy-dispersive X-ray analysis; ion exchange; pH; scanning electron microscopy; sorbents; surface area; titanium dioxide; ultrasonics; wastewater
Abstract:
... Simultaneous removal of cations and anions in wastewater has always been a great concerned environmental problem. In this study, a friendly and inexpensive biosorbent to simultaneously remove Cd(II) and As(V) from aqueous solution was synthesized by ultrasonic biochar and nanoscale TiO2 (TD), and the obtained sorbent was named as BCTD. The maximum sorption capacities of Cd (72.62 mg/g) and As (118 ...

Subject:
X-ray diffraction; X-ray photoelectron spectroscopy; absorption; anions; cations; crops; crystals; irradiation; lamps; metals; nitrogen; oxides; phosphorus; red light; seeds
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 ...
