The adsorption of methylene blue onto bentonite in a batch adsorber has been studied. Three kinetic models, the intraparticle diffusion equation and the pseudo first and second order equations, were selected to follow the ...

An attempt to alleviate the problem caused by the presence of metal complex dyes, mostly used in textile industries, in the textile effluents was undertaken. The effects of adsorbent particle size, pH, adsorbent dose, ...

The sorption of three disperse dyes, namely, Disperse Blue 56 (DB56), Disperse Red 74 (DR74) and Disperse Yellow 119 (DY119), onto alunite has been studied in terms of pseudo-first- and second-order sorptions and intraparticle ...

Adsorption of disperse dyes from aqueous solutions onto calcined alunite has been investigated to assess the possibility of using alunite for removing disperse dyes from aqueous solutions. The effects of particle size, ...

The dissolution of calcined alunite ore in NaOH solution was studied at temperatures ranging between 295-383 K. The effects of ore calcination time and temperature, reaction time and temperature, particle size and solid-liquid ...
