A comparative study of dye removal using fly ash treated by different methods
Abstract
The effect of different methods for fly ash treatment using conventional chemical, sonochemical and microwave method on dye adsorption in aqueous solution was investigated. Three basic dyes, methylene blue, crystal violet and rhodamine B, are employed for adsorption testing. It is found that fly ash shows different adsorption capacity depending on type of dyes. Chemical treatment using HCl will increase the adsorption capacity. The adsorption capacity of HCl treated fly ash varies with the preparation conditions. Microwave treatment is a fast and efficient method while producing the sample with the highest adsorption capacity. Solution pH and inorganic salts in dye solution can significantly influence the adsorption. The adsorption data have been analysed using Langmuir, Freundlich and Redlich-Peterson isotherms. The results indicate that the Freundlich and Redlich-Peterson models provide the better correlations with the experimental data.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
