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.

Application of gas adsorption kinetics. I. A theoretical model for respirator cartridge service life.
Young Hee Yoon,James H. Nelson +1 more
TL;DR: A new theoretical model addressing the adsorption and breakthrough of contaminant vapors or gases with respect to solid sorbents is developed, less complicated and easier to apply to practical industrial hygiene problems than theories developed previously.

Hexavalent chromium removal from aqueous medium by activated carbon prepared from peanut shell: Adsorption kinetics, equilibrium and thermodynamic studies
TL;DR: In this article, the effects of pH, contact time, initial concentration of adsorbate and temperature on adsorption of activated carbon were investigated, and the results showed that both Langmuir and Freundlich models fitted the data reasonably but the Langmuirusorption isotherm model fitted better in the temperature range studied.
