Ni-alginate hydrogel beads for establishing breakthrough curves of lead ions removal from aqueous solutions
TL;DR: In this paper , the authors used Ni-alginate as a selective sorbent for lead ions in a fixed-bed column for the sorption process, and the results for that efficiency are presented as breakthrough curves in view of the impact of various parameters; influent flow rate (1.5, 3.0, and 5.0 mL/min).

Column adsorption study for the removal of phenol from aqueous medium using agro-residue adsorbent
TL;DR: In this article, the potential of activated carbon produced from black gram husk (BGH) for the removal of aqueous phenol in a fixed column was investigated, and the study of breakthrough time and adsorption capacity augmented with an increase in bed height and minimized with the increase in rate of flow, initial concentration of phenol, and size of the particle.

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.

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.
