Non-conventional sorbents for the dye removal from waters: Mechanisms and sepected applications

Popis výsledku v původním jazyce

Synthetic dyes that are extensively used in various industrial branches represent a serious environmental problem when they are emitted into the effluents as they are hardly biodegradable in conventional wastewater treatment plants. Therefore, alternative methods for decolouration of the wastewaters are developed, among them adsorption on solid sorbents is one of the most effective ones. Because the conventional sorbents such as activated carbon are rather expensive for large-scale applications, variouslow-cost materials have been tested as alternative non-conventional sorbents for the dye removal from waters. Effects of principal operational parameters on the dye sorption are discussed in the article, such as an effect of pH (governing both the dissociation/protonation of the active groups on the sorbent surface as well as side equilibria in solution), the presence of inorganic salts or surfactants. Basic equations describing the sorption equilibria (sorption isotherms) as well as so
