TLDR
In this paper, three adsorbents, namely, bentonite-alginate beads, activated carbon-bentonite alginates beads, and activated carbon activated carbon carbon-binite-antilinate beads (ABA), were prepared for the adsorption of methylene blue (MB) and the effects of solution pH, temperature, initial concentration and contact time were investigated.About:

On the comparison of pseudo-first order and pseudo-second order rate laws in the modeling of adsorption kinetics
TL;DR: In this paper, a different method is proposed to analyze experimental results and it is employed here to reexamine experimental data taken from the literature, and it appears that the method generally used is flawed and that it unfairly favors 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.
