Surface treatment- and calcination temperature-dependent adsorption of methyl orange molecules in wastewater on self-standing alumina nanofiber films

Abstract

A novel form of alumina, free-standing and transparent alumina nanofiber thin films has been synthesized and utilized as highly efficient adsorbents for organic dye removal and decoloration, and their adsorption capacities are sensitively dependent on surface treatment and calcination temperature. Compared with commercial alumina powders, the films exhibited totally different adsorption behaviors and enhanced adsorption capacities, which may originate from their different pore sizes in the two forms. The as-prepared dye-adsorbed alumina nanofiber films may open up new possibilities for some potential applications, e.g., pH indicator paper for pH testing derived from the dye-adsorbed alumina films was enabled based on different dye-desorption characteristics in different solutions.
