TL;DR: In this paper, the adsorption mechanism of three reactive azo dyes (Reactive Black 5, Red 239 and Yellow 176) by two natural mezoporous minerals has been examined in order to identify the ability of these minerals to remove coloured textile dyes from wastewaters.

TL;DR: There is a significant potential for the natural Turkish clinoptilolite as an adsorbent material for ammonium removal from aqueous solutions and the Langmuir model agrees very well with experimental data.

TL;DR: In this paper, the adsorption of reactive dyes into zeolite was investigated by a series of batch adaption experiments, and the results indicated that natural Zeolite has a limited adsorptive capacity for reactive dye but can be distinctly improved by modifying its surfaces with quaternary amines.

TL;DR: Examination of the dye removal under the optimum modification conditions reveals that the black dye gives the highest breakthrough point among the three dyes tested, which is ascribed to the hydrophobic/hydrophilic match of the zeolite surface with the dye molecule, which depends upon the way zeolites is modified with HTAB.

TL;DR: Bottle adsorption tests conducted with untreated, acid- and heat-activated sepiolites exhibit two distinct regions, and the observed differences are explained on the basis of partial collapse of the sepiolite crystal structure, the removal of zeolitic and bound waters and modification of the pore size distribution of sepiolate upon treatments.
