PVA/PDADMAC/ZSM-5 zeolite hybrid matrix membranes for dye adsorption: Fabrication, characterization, adsorption, kinetics and antimicrobial properties
R. Sabarish,G. Unnikrishnan +1 more
TL;DR: In this article, a poly vinyl alcohol/poly/poly (diallyldimethylammonium chloride)/ZSM-5 zeolite (PVA/PDADMAC/ZSM5) membranes have been prepared by solvent casting route and the results indicate that the adsorption of methyl orange (MO) dye on the membrane follows pseudo-second-order kinetics.

The adsorption of gases on plane surfaces of glass, mica and platinum.
TL;DR: In this article, the absorption index at the wave length of the band maximum was found to be proportional to the total concentration of metal at shorter wave lengths, however, deviations were observed, the absorption increasing more rapidly with concentration than Beers' law would demand.

Kinetics of Adsorption on Carbon from Solution
Walter J. Weber,J. C. Morris +1 more
TL;DR: In this paper, it was shown that the rate of adsorption of persistent organic compounds on granular carbon is quite low and the rate is partially a function of the pore size distribution of the adsorbent, of the molecular size and configuration of the solute, and of the relative electrokinetic properties of adsorbate and adsorbents.

Yuh-Shan Ho,Gordon McKay +1 more
TL;DR: In this paper, the sorption of two dyes, namely Basic Blue 69 and Acid Blue 25 onto peat has been studied in terms of pseudo-second order and first order mechanisms for chemical sorption as well as an intraparticle diffusion mechanism process.
