| Popis: | Adsorption of Basic Yellow 2 (BY2) onto manure ash, a waste substance, was studied in batch and fixed-bed studies. In both systems, experiments were conducted by using the UV–visible spectroscopy and by examining the effect of different parameters. In order to obtain the adsorption mechanism of manure ash, its microstructure information must be studied. Surface area, particle size distribution (PSD), and structure of adsorbent were studied with Fourier transform infrared spectroscopy, transmission electron microscopy, and PSD. The surface measurement such as specific surface area and pore volume was measured and calculated using BET method. Nitrogen sorption measurements were employed to investigate the variation in surface and pores properties before and after dye adsorption. The experimental isotherm data were analyzed using Langmuir, Freundlich, Dubinin–Radushkevich (D–R), Temkin, Harkins–Jura, and Frumkin isotherm equations, but high correlation coefficients (R2) confirmed the validity of Lang... |
