| Abstract | CoAl?layered double oxide derived from calcination of CoAl?layered double hydroxide at 400? for 120 min, delivered the change in microstructure with increasing surface area. Spinel Co3O4 was the majority in the product as confirmed by X-ray diffraction, and Fourier transform infrared and UV-visible spectroscopies. The calcined product, CoAl?layered double oxide resulted in significant adsorption capacity on dye removal superior to that of CoAl?layered double hydroxide. The adsorbed amounts of the diverse dyes increased as follows: methylene blue < phenolphthalein < methyl orange < orange II. The adsorption affinity between adsorbent and dyes relied on electrostatic interaction and physical adsorption. |
